▼ The aim of future dynamic machine development is to make them lighter, move faster, use less energy, be more human-friendly, and be more adaptable. A promising solution is distributed actuation integrated with load-bearing structures, which can potentially provide better static and dynamic performance, redundancy and more adaptability than current designs. Such structures can be referred to as smart structures. A morphing aircraft wing is a good example for the application of smart structures, which is deemed to provide better aerodynamic performance and higher wing efficiency than conventional designs. A tensegrity structure is a strong candidate for this integration due to its potentially high stiffness-to-mass ratio and inherent advantage of being a multi-element structure, into which actuators can be embedded. The research presented in this thesis concerns the study of a smart structure, and its integration with a morphing aircraft wing. A structure design method has been developed for an active tensegrity structure. The high external load level and actuator size constraints are the main challenges at the design stage. A case study design for a smart structure integrated in a morphing wing to be tested in the University of Bath wind tunnel is presented. A forward kinematic calculation method has been developed to transform the actuator axial displacements to structure shape changing degree of freedom (DOF) form. Six actuators and four shape-changing DOF are considered in the analysis, and two internal load paths are also under closed loop control. An antagonistic multi-axial control scheme has been developed for the smart structure, which is capable of motion and internal force control. An experimental smart structure prototype has been built, along with the morphing wing assembly. Pneumatic cylinders are embedded into the structure; switching valves are selected for the pneumatic control. A simulation model is developed for the prototype, including a dynamic model for the pneumatic system and a multi-body simulation for the structure. The dynamic behaviour of the smart structure has been investigated via a series of simulations and experiments. The wind tunnel test results have demonstrated that the prototype morphing wing is capable of accurate shape- changing control, and offering reasonable aerodynamic performance, while maintaining a desired level of internal load in a stiff structure, with different wind speeds.

▼ It is believed that structures and actuation systems should be tightly integrated together in the future to create fast moving, efficient, lightweight dynamic machines. Such actuated structures could be used for morphing aircraft wings, lightweight actuated space structures, or in robotics. This requires actuators to be distributed through the structure. A tensegrity structure is a very promising candidate for this future integration due to its potentially excellent stiffness and strength-to-weight ratio, and the inherent advantage of being a multi-element structure into which actuators can be embedded. Development of these machines will utilise expertise in several fields, involving kinematics, dynamics, actuation and multi-axis motion control. The research presented in this thesis concerns the study of multi-axis actuated tensegrity structures. A form-finding method has been developed to find stable geometries and determine stiffness properties of the type of tensegrity structure proposed. It has been shown that a tensegrity structure, with practical nodes of finite size, can be designed with actuated members to give shape-changing properties while potentially allowing a good stiffness to mass ratio. An antagonistic multi-axis control scheme has been developed for the tensegrity structure. The describing function technique has been used to analyse the dead band controller in the control scheme, giving a stability criterion. An experimental actuated tensegrity system has been designed and built incorporating pneumatic muscles controlled by switching valves. Mathematical models for the experimental actuated tensegrity system have been developed in detail, including the pneumatic actuation system and the structure geometry. The dynamic behaviour of the tensegrity system has been investigated via several simulation studies, using the developed models and the proposed control scheme. Experimental validation has been successfully conducted. The multi-axis control scheme can accurately control the tensegrity structure to achieve shape changes while maintaining a desired level of internal pre-load. The mathematical models can be used as a basis for further development.

▼ Atomic force microscopy has been the primary workhorse for imaging and manipulating samples with sub-nanometer resolution and pico-Newton scale force resolution. It has found applications in such diverse fields as biology, chemistry, engineering, medicine, and physics. The central feature of atomic force microscopy (AFM) is its probing system that detects the near-field physical interactions between the probe tip and the sample. In principle, 3D forces can be detected and controlled. However, the overwhelming majority of the applications of AFM, in every field where it is used, are on samples which are very nearly planar and horizontal. The primary reason for this severe constraint on the possible samples that can be imaged or manipulated by AFM is due to the geometry of the probe. In this research, the design, actuation, and control of a novel multi-axis probing system, which can simultaneously control the tip position and tip orientation, and which enables imaging and manipulation of samples having three-dimensional geometries, is investigated. It can change the orientation of the tip according to the surface normal of the sample, and thus precisely control the tip-sample interaction point when imaging surfaces having large topographic variations. It leads to the creation of a multi-axis probing system for nano-metrology, which is a three-dimensional (3D) surface tool rather than a two-dimensional (2D) planar surface tool. In order to fully develop the probing system, two more innovations are proposed. Firstly, a multi-axes scanning scheme is developed in order to align the directions of scanning and interaction control depending on the local surface orientation. Secondly, a tip-sample interaction scheme is proposed that regulates the direction of the tip-sample interaction while minimizing the effect of lateral friction. A robust control scheme is implemented in combination with these proposed developments, which commands the tip to track orientation changes of the sample surface when imaging 3D samples. The integrated system possesses two unique features, namely, multi-axis control of tip and scanning operation and the capability to interact with 3D surfaces in a gentle, controlled manner. The probing system is evaluated by imaging a variety of engineered 3D surfaces. The result of scanning a micro-pipette of diameter 2.4µm using this tool is presented and discussed.

Les actionneurs piézoélectriques font partie des outils les plus utilisés dans les applications à l'échelle micro/nano-métrique (micromanipulation, microassemblage, micropositionnement, etc…). Du point de vue fonctionnel, on distingue les actionneurs mono-axe (permettant d'obtenir la déflection suivant une direction) et les actionneurs multi-axes (pouvant fléchir suivant plusieurs directions). La notoriété des actionneurs piézoélectriques est due à un certain nombre de performances telles qu'une large bande passante (plus du kHz possible), une très bonne résolution (de l'ordre du nanomètre), une faible consommation en énergie électrique, une grande densité de force, une facilité d'alimentation et d'intégration, etc. Cependant, ces actionneurs sont caractérisés par des non-linéarités fortes (hystérésis et la dérive lente), des oscillations mal-amorties, et sont sensibles à la variation des conditions ambiantes (en particulier à la variation de la température). Pour les actionneurs multi-axes, il s'ajoute un problème des couplages entre les différents axes de l'actionneur. Cette thèse propose des stratégies innovantes de commande des actionneurs piézoélectriques multi-axes pour contrer les problèmes sus-mentionnés. Ces stratégies sont groupées en deux catégories. La première catégorie concerne les techniques de commande en boucle fermée. Ces techniques sont les plus adaptées pour garantir la robustesse et un niveau de précision élevé pour les actionneurs piézoélectriques. Cependant, à l'échelle micro/nano-métrique, ces techniques sont limitées par un manque d'espace suffisant pour installer des capteurs de position. La deuxième catégorie concerne la commande en boucle ouverte dont l'intérêt majeur est lié au fait qu'il n'y a pas besoin de capteurs pour la commande, ce qui constitue un avantage en terme de coût et facilité d'intégration. Dans cette thèse, nous proposons d'abord les techniques de modélisation et de commande en boucle ouverte multivariables. Ensuite, nous faisons une analyse des effets de la température sur les actionneurs piézoélectriques et nous proposons des techniques de commande en boucle ouverte et en boucle fermée de ces effets. Enfin, une stratégie de commande en boucle fermée par découplage, visant à obtenir des correcteurs d'ordre réduit pour les actionneurs multi-axes est proposée. Toutes ces techniques sont vérifiées et appliquées expérimentalement à un actionneur piézoélectrique de type tube.

Piezoelectric actuators are among the most used tools in many applications at micro/nano-scale (micromanipulation,microassembly, micropositioning, etc). From a functional perspective, there exist mono-axis actuators(which are made to bend in one direction) and multi-axis actuators (which provide deflections in different directions).The popularity of piezoelectric actuators is especially due to their high resolution (nanometric resolution),the large bandwidth (greater than 1kHz possible), the low electrical power consumption, the high force density,the ease of integration in positioning systems, etc.…

Magistrsko delo opisuje načrtovanje, izvedbo in delovanje linearne elektro-hidravlične enote za merjenje in regulacijo sile. Takšne sisteme pogosto najdemo v industriji, saj hidravlika omogoča velike sile z relativno majhnimi stroji. Enota je sestavljena iz hidravličnih in električnih komponent. Prve skrbijo za prenos in pretvorbo energije, druge za napajanje, nadzor in varnost. V delu bodo opisane tri možnosti merjenja sile, in sicer: lasten senzor z merilnimi lističi, merilna celica sile in meritev sile s pomočjo razlike tlakov v komorah valja. Na ta način izmerjeno silo nato uporabimo pri povratni zanki regulacije sile. Regulacijo sile potrebujemo kasneje za avtomatizacijo preizkuševališča za določanje dinamične trdnosti materialov. Za krmiljenje komponent je vgrajen krmilnik proizvajalca Beckhoff tipa CX5140. Gre za zmogljiv večjedrni krmilnik, ki poganja operacijski sistem Windows Embedded Standard. Na njem se izvaja program zgrajen v programskem okolju Twincat 3. Za vmesnik človek-stroj smo izdelali še program v Visual Studio C# , ki poleg interakcije izvaja še nekatere druge funkcije.

The master thesis describes the design, implementation and operation of linear electro-hydraulic unit for force measurement and control. Such systems are often found in the industry, mostly because the usage of hydraulics enables production of large forces with relatively small machines. The unit consists of hydraulic and electrical components. First take care of the transmission and conversion of energy, the other for power supply, control and security. Three options for measuring force are described in the section: handmade sensor with strain gauges, load cell and force measurement with pressure difference in cylinder chambers. Measured force information enables implementation of closed loop force control, which is needed for the automation of a test station to determine the dynamic strength of the materials. PLC used to control components in test application is Beckhoff CX5140. It's a powerful multicore controller running Windows Embedded Standard. Control program for test station was written in Twincat 3 and is running on controller. We also developed a program for the human-machine interface, which was written in Visual Studio C# programming language. In addition to interaction, it also implements some other functions.

▼ Additive Manufacturing (AM) has become a well-recognized method of manufacturing and has steadily become more accessible as it allows designers to prototype ideas, products and structures unconceivable with subtractive manufacturing techniques for both consumer grade and industrial grade applications. Commonly used thermoplastics for 3D printing have properties that may not be sufficient to comply with the application’s certification requirements, or their performance is less than desirable for aerospace and other high performance applications. Additionally, additively manufactured parts have reduced mechanical properties in the build direction of the print, and are generally weaker than their equivalent injection-molded parts. Furthermore, Computer Aided Design and Manufacturing (CAD/CAM) tools have evolved together with the evolution of processes for subtractive and deformative based manufacturing methods, and ply-based additive composite manufacturing. For AM to gain more traction in industrial engineering environments, the process specific algorithms for AM need to be implemented in CAD/CAM software. There is therefore a need for reinforcement of both the material and the structures, and for proving the industrial capabilities of additive manufacturing, in particular fused filament fabrication, through a new set of processes that complement the existing design paradigm. A promising solution to the above mentioned problems of strength is using engineering thermoplastics and through the addition of continuous carbon fibers in the print. Unfortunately, engineering-thermoplastic impregnated continuous carbon fiber filaments for 3D printing do not exist due to the low demand and pure filament is currently only available for proprietary printers at steep prices. Additional strength increase in the inter-layer direction may come through the addition of local reinforcement deposited on an existing structure in the build direction, which implies stepping away from layer-by-layer manufacturing and manufacturing using true 3D deposition and toolpathing. This is only possible by exploiting the full benefits of a 6 or higher degree of freedom printing system. In this research, a KUKA robotic platform capable of motion with 6 degrees of freedom is used as a base to develop a multi-axis, industrial-scale 3d printer. Polyetherimide (PEI), an engineering thermoplastic sold under the Sabic brandname ULTEM 1000 was acquired in pellet form and extruded within tolerances into a usable 3D printing filament. ULTEM 1000-Continuous Carbon Fiber filament was developed by dissolving the ULTEM 1000 pellets in a solution bath and consequently pulling the carbon fiber through it. A specialized nozzle design and printing bed capable of going up the required processing temperatures was developed and integrated with the KUKA platform, for which specialized toolpathing software was written. The toolpathing software consists of two subsets: a slicing tool that allows multi-orientation slicing, and a translation parser which converts the… Advisors/Committee Members: Ramy Harik, Michel van Tooren.

▼ Thermal oil oxidation is an important reason for the engine oil degradation in trucks. Having a comprehensive model that includes all the influential factors while it is feasible for being implemented in the ECUs, was aimed for this work. Therefore, the chemical investigating of the problem leaded to propose a first kinetic model and its thermal analysis caused modelling the oil thermal behaviour. The latter was developed for four compartments: Bearings, turbocharger, piston cooling and oil sump in the oil path through the lubrication system, because the highest oil temperature happens due to friction, combustion of fuels and exhaust gas transportation. Independency from the design parameters of the compartments and simplicity of models for the ECU implementation caused to investigate two various modelling hybrid approach: physical modelling and control theory approach. The first one was done for the bearings and piston cooling, and showed a high level of complexity leading to switch to the second approach. The latter was applied for all compartments while it satisfied requested requirements. To adjust and evaluate the models, an experimental campaign was devoted to acquiring the needed parameters with consideration of the project budget. Also using the previous simulation and experimental efforts at the company provided a possibility to develop flow rate sub-models used in the thermal modelling. The proposed model for all compartments, well predicted the oil thermal behaviour for both stationary and dynamic operating conditions. A comparison between the experimental data for the oil in the oil sump and turbo charger was done to show the reliability of the related models in both stationary and transient statuses. For the bearings, the simulation data for stationary condition were applied as a reference. The modelled oil temperature after piston cooling was compared to a set of experimental data that presented the probable temperature in some conditions close to stationary operating points.

▼ In the past decade, distributed real-time and embedded (DRE) systems have emerged as an interesting and challenging class of target applications within the mission critical software domain. Examples of existing DRE systems include air traffic management systems, cyber-physical systems composed of sensors and actuators in cooperating teams of robots, industrial control systems, lunar rovers, flight control computers, and total ship computing environments. Each of these systems has its own set of special challenges, but most are characterized by stringent quality-of-service requirements despite scarce resource availability, connectivity, and control. With the push toward multi-core and cloud computing initiatives, deployment and testing of distributed, real-time and embedded (DRE) systems has become even more complex. If DRE system developers are to harness highly parallel, anonymous systems for DRE deployment and testing, more tools and techniques are necessary for control of deployment and testing information, resources, and quality-of-service. Current deployment systems for DRE are highly specialized toward one shot deployments of DRE systems as specified at design time. Consequently, because of the ever-changing nature of mission critical deployments and hardware, static design-time deployments may not reflect the real nature of the targeted testbed, or even worse, the real-world deployment environment as it regards to latency and resource availability in the network. Moreover, the deployment solutions do not provide developers with the right set of tools for sequencing and automating tests for validating the DRE system before it goes live. Additionally, once a deployment is live, conditions in the network may deteriorate until the DRE system is ineffective. We believe better solutions are possible that allow for DRE systems to self-heal and redeploy themselves according to high-level workflows provided by users. This dissertation presents a set of research contributions to the area of deployment and testing frameworks for DRE systems and results from deployment and testing research and tools developed under the QED and AMMO projects at ISIS. First, a reasoning engine for distributed, real time systems is presented for monitoring and mutating DRE system environment information with microsecond latencies on evaluation and dissemination. This reasoning engine is used extensively in our deployment and testing solutions to provide fast, fine-grained control over decision-making processes during testing and deployment. Second, we detail a quality-of-service-enabled distributed mutual exclusion algorithm which allows DRE system developers to decrease latency of resource acquisition for important applications or components in a deployment or testing scenario. Next, we describe research into a deployment and testing framework that harnesses the reasoning engine for sequencing and coordinating activities between processes in the DRE system. Lastly, we describe the development of heuristic-based approaches for… Advisors/Committee Members: Douglas Schmidt (committee member), Sandeep Neema (committee member), Janos Sztipanovits (committee member), Gabor Karsai (committee member), Aniruddha Gokhale (Committee Chair).

The existing powertrain control system in Volvo CE's vehicles consists of various types of physical quantities that are controlled. One of them is the engine speed. The purpose of this thesis is to investigate whether there are other control strategies suitable for engine speed control, than the existing one. Currently, the existing control system requires re-calibration of the control parameters if hardware in the vehicle is replaced. The current controller is a gain-scheduled PID controller with control parameters that varies over the operating range. The aim has been to develop several different adaptive control strategies. Adaptive control methods are expected to adapt to the changes of the system that a replacement of hardware can bring. The performance and robustness of the developed controllers have been compared with the existing controller. The approach has been to implement the control strategies in Matlab/Simulink and simulate the process with existing engine software provided by Volvo CE. The next step was to test and verify the controllers in a real machine. The focus in this thesis work has been on the adaptive control strategies MRAC (Model-Reference Adaptive Control) and L1 Adaptive Control. In the MRAC structure the desired performance is specified in terms of a reference model that the real system is supposed to follow. Each time an error is generated, by comparing actual and desired output, a suitable algorithm is used in order to obtain the control signal that can minimize the error. In addition, modeling errors and disturbances are estimated so that the controller can compensate for these. L1 Adaptive Control is an extension of the MRAC structure. The difference is that before the control signal is fed to the real system, it is low-pass filtered. This is done in order to prevent feeding high frequencies into the system. The results show that adaptive control has potential to be used in engine speed control. Reference following and disturbance rejection is well handled and simulations have furthermore shown that the developed controllers can deal with changes in the hardware. One of the developed L1-controllers was implemented in a real machine with promising results.

Det existerande styrsystemet i Volvo CE:s maskiner har till uppgift att styra och reglera flera olika fysikaliska storheter. En av dessa storheter är motorvarvtalet. Syftet med detta examensarbete är att undersöka alternativa reglerstrategier som kan användas för att styra motorvarvtalet. Problemet idag är att det nuvarande styrsystemet kräver omkalibrering av regulatorparametrar när befintlig hårdvara i maskinen behöver ersättas på grund av föråldring eller slitage. Den nuvarande regulatorn är en parameterstyrd PID-regulator där regulatorparametrarna beror av aktuell arbetspunkt. Målet har varit att utveckla och prova flera olika adaptiva reglerstrategier. Dessa metoder förväntas kunna hantera förändringar och adaptera sig mot nya förhållanden och omständigheter som en hårdvaruförändring kan…

▼ Micro Combined Heat and Power systems or microCHP systems generate heat and electricity for a home. Stirling engines are widely used as prime movers in microCHP applications. Stirling engine is an external combustion engine having an enclosed working fluid (as helium) that is alternately compressed and expanded to operate a piston. The displacer shuttles the working fluid between the hot and cold ends. The piston is coupled to a transmission and to an electrical machine to generate power. Conventional Stirling engines are not controllable to a great degree. The piston and displacer are connected to the same crank and they maintain the same phase difference throughout the cycle. Also the piston and displacer are normally constructed to move in a sinusoidal fashion. The Active Stirling Engine is a new concept introduced in this thesis which has a free displacer. The displacer is driven separately compared to a coupled drive in conventional Stirling engines. The displacer motion can be non-linear with dwell at each ends of the stroke, opening up the possibilities to increase the pressure volume diagram which indicates the work done by the engine. A separately driven displacer also allows introducing phase control and stroke control to improve the controllability of a Stirling engine. This thesis examines the effect of non-linear displacer motion and phase control of the displacer on Stirling engine performance. Simulations are performed in Sage, the leading Stirling engine simulation software, to understand the effect of displacer phase control. A test rig is constructed with the actively controlled displacer connected to a linear machine controlled by a programmable servo. Heat is applied to the test rig though an electric heating coil. The test rig is charged with nitrogen at 20Bar pressure. The power piston is connected to a rotating electrical machine via the transmission. The rotating electrical machine is used to start the engine and to act as the generator. The test rig is instrumented to determine the linear position of the displacer and piston, angular position of the rotating electrical machine shaft, temperatures, pressures and flow. A LabVIEW™ based data acquisition system is set up to capture data from the test rig. Data is collected at various test cases. The simulation result is compared against post processed data. An efficiency improvement of 15% is achieved using this method and is demonstrated experimentally. Applications in micro combined heat and power systems utilising the improved efficiency due to non linear motion and controllability due to phase control are explored in this thesis.

▼ With increasing strain on the civil aviation industry to meet strict targets to reduce the adverse effects aviation has on the environment by 2050, significant advances in aircraft design and research are required. Aerodynamic improvements have been a focus for several decades now, however, current and future civil transport aircraft are based on traditional designs originating from the 1950s. Optimisation of aircraft external geometry for aerodynamic gain is reaching maturity and is becoming increasingly non-cost-effective. New advances in sensor and actuator technology has allowed for the development of active flow control (AFC) devices that have shown promising results in laboratory and even full-scale flight conditions, as seen by the joint NASA-Boeing ecoDemonstrator. One such device is the synthetic jet actuator (SJA), that synthesises periodic jets without the requirement for external air supply, while adding momentum to the surrounding flow. For this reason, SJAs are also referred to as zero-net-mass-flux actuators. There exists extensive work on the use of these devices for flow control applications in a laboratory setting. One of the key issues that remains unresolved, hindering successful aircraft application to-date, is the actuator self-noise generated. The noise level of SJAs can be so severe that they were rejected for application on the ecoDemonstrator in favour of a higher authority, quieter AFC device. SJAs were only considered for use in emergency situations on aircraft. Furthermore, the actuators were also not permitted to operate simultaneously at full power, which may severely limit scope for flow control on aircraft. Other applications that would benefit from SJAs include heat transfer for cooling in electronic devices. Studies in this field identify the same problem with noise levels of up to 73 dB reported. It is clear that work towards the self-noise reduction of SJAs is required to harness the full potential of this actuator technology. In the work presented, passive and active noise control measures in the form of lobed orifices and antiphase operation of two jets, respectively, on the noise reduction of SJAs are ii investigated. Noise sources of synthetic jet actuators include mechanical (diaphragm) and jet induced noise, where the focus of this work is on the latter type. Tests were conducted in quiescent conditions using jet velocity measurements, acoustic measurements, and flow visualisation. Tests were carried out using a single chamber SJA with variable cavity height and both circular and lobed orifices. These tests helped identify a SJA self-noise generation mechanism when using a circular orifice. This mechanism is characterised by a constant frequency behaviour visible in acoustic spectra for a specific jet Reynolds number range of 600 < Rej < 750 and Strouhal number range of 0.22 < St < 0.50. The geometries of the lobed orifices used in this work differ in lobe count and penetration. It was shown that a broadband noise reduction is possible with such orifices, with a maximum…
