ENGLISH ABSTRACT: The slip synchronous-permanent magnet generator (SS-PMG) is a direct-driven, direct-to-grid generator for wind turbine applications. This investigation focuses on achieving automated grid connection and low voltage ride-through for a small-scale SS-PMG. To reduce cost and complexity, components such as blade pitch controllers and frequency converters are avoided. Instead, electromagnetic braking is employed to control turbine speed prior to grid synchronisation and compensation resistances are used to facilitate grid fault ride-through. The conditions under which the SS-PMG can be successfully synchronised with the grid are determined, indicating a need for speed control. An evaluation of electromagnetic braking strategies reveals that satisfactory speed control performance can be achieved when employing back-to-back thyristors to switch in the braking load. Simulations show that controlled synchronisation can be executed successfully under turbulent wind conditions. All controllable parameters are held within safe limits, but the SS-PMG terminal voltage drop is higher than desired. Compensation is developed to allow the SS-PMG to ride through the voltage dip profile specified by the Irish distribution code. It is found that a combination of series and shunt resistances is necessary to shield the SS-PMG from the voltage dip, while balancing active power transfer. The flexibility offered by thyristor switching of the shunt braking load is instrumental in coping with turbulent wind conditions and unbalanced dips. The South African voltage dip profile is also managed with conditional success. Following on from the theoretical design, the grid connection controller is implemented for practical testing purposes. Protection functions are developed to ensure safe operation under various contingencies. Before testing, problems with the operation of the thyristors are overcome. Practical testing shows that grid synchronisation can be undertaken safely by obeying the theoretically determined conditions. The speed control mechanism is also shown to achieve acceptable dynamic performance. Finally, the SS-PMG is incorporated into a functioning wind turbine system and automated grid connection is demonstrated under turbulent wind conditions. Future investigations may be focused on optimal control strategies, alternative solid-state switching schemes, and reactive power control. Low voltage ride-through should also be optimised for the South African dip profile and validated experimentally.

▼ Osnovni zahtevi koji se postavljaju pred današnje kočne sisteme motornih i priključnih vozila, u pogledu bezbednosti vozila i saobraćaja, se odnose na njihovo dalje unapređenje kroz razvoj novih, inteligentnih, rešenja. Suština ovih zahteva jeste da se omogući pomoć vozaču kroz inteligentno upravljanje sistemima na vozilu, odnosno njihovim performansama u različitim, dinamički promenljivim, radnim uslovima. Pošto kočne performanse vozila zavise od performansi kočnica, koje funkcionišu na principima trenja i samim tim imaju vrlo nepredvidiv karakter, i od usklađenosti tih performansi sa trenutnim uslovima prijanjanja u kontaktu pneumatika sa tlom, koji se mogu intenzivno menjati tokom samo jednog ciklusa kočenja, realizacija ovih zahteva je izuzetno kompleksna. To je osnovni razlog za sprovođenje istraživanja u pogledu razvoja i implementacije inteligentnijih načina upravljanja performansama kočnog sistema na osnovu uslova prijanjanja u kontaktu pneumatik–tlo. U ovoj doktorskoj disertaciji su istraživane mogućnosti primene tehnika iz oblasti veštačke inteligencije u cilju modeliranja složenih dinamičkih uticaja radnih režima kočnica motornih vozila i uslova u kontaktu pneumatik–tlo, kao i predviđanja ovih uticaja u cilju upravljanja performansama kočnica, a time i performansama kočnog sistema, u toku ciklusa kočenja. Zbog nemogućnosti modeliranja složenih dinamičkih uticaja radnih režima kočnica motornih vozila na njihove izlazne performanse, odnosno na vrednosti klizanja u kontaktu pneumatika i puta pomoću klasičnih matematičkih metoda, uvedena je nova inteligentna metoda bazirana na dinamičkim veštačkim neuronskim mrežama i fazi logici. U skladu sa time, u ovoj disertaciji su istraživane mogućnosti primene dinamičkih veštačkih neuronskih mreža i fazi logike u cilju modeliranja, predviđanja i inteligentnog upravljanja performansama kočnica, odnosno performansama kočnog sistema. Predmetno istraživanje je usmereno ka razvoju sposobnosti kočnog sistema ka inteligentnom prilagođavanju sile kočenja dinamičkim promenama podužnog klizanja točka (pneumatika) u kontaktu sa putem u toku ciklusa kočenja. Ovakav koncept upravljanja performansama kočnog sistema, na osnovu prethodnih i trenutnih vrednosti posmatranih uticajnih veličina i identifikovanih uslova prijanjanja tokom kočenja, podrazumeva predviđanje potrebne vrednosti pritisaka aktiviranja kočnica, na prednjoj i zadnjoj osovini, za date uslove kočenja (vrednosti pritiska aktiviranja kočnice, vrednosti brzine točka na prednjoj/zadnjoj osovini, temperature u kontaktu frikcionog para kočnice na prednjoj/zadnjoj osovini i vrednosti klizanja u kontaktu pneumatik–tlo) kako bi se u kontaktu pneumatika i tla postiglo željeno (optimalno) klizanje u podužnom pravcu.

▼ The increasing growth of population and a rising number of vehicles, connected to an individual, demand new solutions to reduce traffic delays and enhance road safety. Autonomous Vehicles (AVs) have been considered as an optimal solution to overcome those problems. Despite the remarkable research and development progress in the area of (semi) AVs over the last decades, there is still concern that occupants may not feel safe and comfortable due to the robot-like driving behaviour of the current technology. In order to facilitate their rapid uptake and market penetration, ride comfort in AVs must be ensured. Braking behaviour has been identified to be a crucial factor in ride comfort. There is a dearth of research on which factors affect the braking behaviour and the comfort level while braking and which braking profiles make the occupants feel safe and comfortable. Therefore, the primary aim of this thesis is to model the deceleration events of drivers under normal driving conditions to guide comfortable braking design. The aim was achieved by exploiting naturalistic driving data from three projects: (1) the Pan-European TeleFOT (Field Operational Tests of Aftermarket and Nomadic Devices in Vehicles) project, (2) the Field Operational Test (FOT) conducted by Loughborough University and Original Equipment Manufacturer (OEM), and (3) the UDRIVE Naturalistic Driving Study. A total of about 35 million observations were examined from 86 different drivers and 644 different trips resulting in almost 10,000 deceleration events for the braking features analysis and 21,600 deceleration events for the comfort level analysis. Since deceleration events are nested within trips and trips within drivers, multilevel mixed-effects linear models were employed to develop relationships between deceleration value and duration and the factors influencing them. The examined factors were kinematics, situational, driver and trip characteristics with the first two categories to affect the most the deceleration features. More specifically, the initial speed and the reason for braking play a significant role, whereas the driver's characteristics, i.e. the age and gender do not affect the deceleration features, except for driver's experience which significantly affects the deceleration duration. An algorithm was developed to calculate the braking profiles, indicating that the most used profile follows smooth braking at the beginning followed by a harder one. Moreover, comfort levels of drivers were analysed using the Mixed Multinomial Logit models to identify the effect of the explanatory factors on the comfort category of braking events. Kinematic factors and especially TTC and time headway (THW) were found to affect the most the comfort level. Particularly, when TTC or THW are increased by 1 second, the odds of the event to be “very comfortable” are respectively 1.03 and 4.5 times higher than being “very uncomfortable”. Moreover, the driver's characteristic, i.e. age and gender affect significantly the comfort level of the deceleration event.…

Platooning is an application of autonomous driving in which the vehicles travel linearly following each other. The benefits of such driving are many-fold, primarily it increases the traffic throughput and also reduces fuel consumption as the result of minimized drag experienced by the vehicles. The state-of-the-art technologies to achieve platooning involve vehicle-to-vehicle communication for receiving all the events instantaneously. However, wireless channels being prone to communication losses pose risks to the platoon operation. Therefore, it is important to study how platoons operate under communication losses. Platoons being vehicular ad-hoc networks, the information dissemination is governed by Time Division Multiple Access policies known as Information Flow Topology (IFT). Platooning being sensitive to communication losses, during an emergency braking, the requirements are even more stringent as it could lead to rear-end collisions within the vehicles. All the performance evaluation are done on a newly designed testbed which is both cost-effective and customizable. Several kinds of IFTs have been developed in recent years. We consider four of the predominant ones and evaluate their performance during emergency braking with temporary communication loss. Since the decrease in inter-vehicle distances is the main reason for vehicle collisions during platoon, we use it as a key performance indicator when evaluating the performance. To improve the reliability of communication in the platoon, we propose to adopt an existing methodology in wireless networking and combine it with the IFTs in platooning. We additionally show the improvement in the collision probability with this method. We conclude our work with limitations and further improvements.

▼ The thesis deals with the possibilities of identifying the relevant tire traces at the place of a traffic accident based on their physical characteristics. Braking traces on the road are one of the most important objective elements for accident analysis, their easy and accurate detection is very important for accurate accident assessment. With the increasing technical equipment of vehicles, especially with the introduction of newer generations of braking assistance systems, traces left by the tires become almost invisible to the human eye. It is therefore highly desirable that their detection should be not only as accurate as possible but also as easy and fast as possible, not only for forensic experts, but especially for members of the traffic police departments. In line with the development and introduction of new safety and assistance systems for vehicles should also be the development of means and methods of providing the basis for technical analysis of traffic accidents. Reality shows that the procedures, even if still functional, are practically identical for several decades, are dependent on the subjective capabilities of the documenting person. An essential element of the work, compared to the previously described measurement procedures, is the use of modern methods and devices at the highest known level of knowledge. The aim is to find and verify a simple, accurate, subjectively least influenced detecting method for tire traces on the road. A series of measurements confirmed the possibility of using the thermal camera at the technical level usually available at the place of the accident, under limited atmospheric and time conditions. In addition, laser-induced plasma spectroscopy and rLIBS were used. This method of detecting spotless tire treads can be marked as a minimally feasible documentary and at the same time as fast enough, based on the measurements made and the intended removal of defects of the instrument in the development phase of the prototype.

▼ In terms of vehicle and traffic safety, the main demands imposed to the braking systems of motor vehicles and trailers are related to their further improvement through development of new, intelligent, solutions. It could enable the driver assistance function through an intelligent control of the vehicle systems performance in different and dynamically changing operating conditions. Since the braking performance of vehicles depend on the performance of the brakes, which based their function on the friction, it is a difficult to control stochastically changed the brakes performance. Furthermore, harmonization of that performance with the actual conditions in the tire-road contact, which is also intensively changed during a braking cycle, the realization of demands towards an intelligent control the braking system performance is very complex. This is the main reason for conducting research regarding development and implementation of more intelligent ways for control of the braking system performance. In this doctoral thesis, possibilities for employing of an artificial intelligence have been investigated in order to model and predict the impact of the brakes operating regimes and the complex conditions in the tire-road contact in order to provide intelligent controlling of the braking system performance during a braking cycle. Due to the impossibility for modeling of complex dynamic influences of brakes’ operating conditions on their performance and consequently on the value of the longitudinal wheel slip using conventional mathematical methods, a new method has been introduced based on an integration of dynamic neural networks and fuzzy logic. Accordingly, this thesis investigated possibilities for the proper integration of dynamic artificial neural networks and fuzzy logic in modeling, prediction, and intelligent control of the brakes’ performance, i.e. performance of the braking system. It should provide inherent capabilities of the braking system towards an intelligent adaptation of the braking forces to the dynamic changes of the longitudinal slip ratio in the tire–road contact during a braking cycle. This concept for control of the braking system performance, based on previous and current values of observed influential factors, means predicting of the brake applied pressure values, on the front and rear axle, for the given braking conditions (brake applied pressure, wheel speed on the front/rear axle, brake interface temperature on the front/rear axle, and wheel slip) in order to achieve the desired and/or optimal slip level in the longitudinal direction. Furthermore, the braking system should continuously learn about the complex and stochastic influences between these factors during a braking cycle. Since this is especially important for commercial vehicles, the focus of research has been directed on possibilities for improving the performance of electronically controlled braking system. It is done not only to achieve the optimal value of the longitudinal wheel slip in the…

▼ Over the past century, cars have become a fundamental part of our society. With the increasingly larger number of vehicles on the road, safety is, now more than ever, a topic of paramount importance. It is estimated that every year 26,000 people are killed on European roads, corresponding to a social cost of 100 billion euros. In the last two decades, awareness about this issue has however increased substantially, and great effort is now put into improving these numbers. The introduction of driver assistance systems in recent years has led to a significant decrease in fatal accidents. One of the first implemented ones was Anti-lock Braking System (ABS), introduced on the market in 1978. ABS is an active safety system nowadays mandated on every new car sold in Europe. By preventing wheel lock during emergency braking, the system allows for shorter braking distances and steering ability retention. Despite the fact that forty years went by since ABS introduction, the control strategy behind it has changed very little, still retaining a rule-based approach. Extensive review of literature of the subject, highlighted the possibility that significant improvements could be achieved if the control strategy was to be redesigned in a way that takes advantage of the many technological improvements achieved in the last decade. The aim in this thesis is to verify this statement and quantify any potential improvement in Anti-lock Braking System. In order to achieve the research objective, a novel ABS algorithm was designed. The controller, based on state-of-the-art hardware, uses a model predictive control approach and potentially available wheel force information as the pillars of its design. A supervisory activation logic is also developed to replicate full ABS functionalities and keep the driver in the loop. The controller is then tested on Toyota’s high-end vehicle simulator and benchmarked against the current industrial state of the art. The vehicle simulator has its core in a multibody model augmented with kinematics and compliance measurements, and it is largely validated against experiments. A complex multi-physics model of the brake system, together with the short wavelength rigid ring tire model, complete the setup. A comprehensive set of manoeuvres, including friction jumps and rough road braking scenarios, is developed to assess performance and robustness of the proposed controller. Additionally, a list of aspect-specific performance metrics is drafted and deployed to accurately investigate the simulations results and identify relative gains with respect to the benchmark in different instances of the braking manoeuvre. The analysis showed substantial reduction of the braking distance and improved steering ability in each of the simulated scenarios. Furthermore, robustness of the controller against external factors, such as high frequency noise generated by road irregularities or friction transitions, is demonstrated to be comparable to that of industrial state of the art controllers. Based on the now… Advisors/Committee Members: Shyrokau, Barys (mentor), Berardo, Giovanni (graduation committee), Babuska, Robert (graduation committee), Baldi, Simone (graduation committee), Ferranti, Laura (graduation committee), Delft University of Technology (degree granting institution).

▼ The application of Model Reference Adaptive Control (MRAC) for train dynamic braking is investigated in order to control dynamic braking forces while remaining within the allowable adhesion and coupler forces. This control method can accurately determine the train braking distance. One of the critical factors in Positive Train Control (PTC) is accurately estimating train braking distance under different operating conditions. Accurate estimation of the braking distance will allow trains to be spaced closer together, with reasonable confidence that they will stop without causing a collision. This study develops a dynamic model of a train consist based on a multibody formulation of railcars, trucks (bogies), and suspensions. The study includes the derivation of the mathematical model and the results of a numerical study in Matlab. A three-railcar model is used for performing a parametric study to evaluate how various elements will affect the train stopping distance from an initial speed. Parameters that can be varied in the model include initial train speed, railcar weight, wheel-rail interface condition, and dynamic braking force. Other parameters included in the model are aerodynamic drag forces and air brake forces. An MRAC system is developed to control the amount of current through traction motors under various wheel/rail adhesion conditions while braking. Minimizing the braking distance of a train requires the dynamic braking forces to be maximized within the available wheel/rail adhesion. Excessively large dynamic braking can cause wheel lockup that can damage the wheels and rail. Excessive braking forces can also cause large buff loads at the couplers. For DC traction motors, an MRAC system is used to control the current supplied to the traction motors. This motor current is directly proportional to the dynamic braking force. In addition, the MRAC system is also used to control the train speed by controlling the synchronous speed of the AC traction motors. The goal of both control systems for DC and AC traction motors is to apply maximum available dynamic braking while avoiding wheel lockup and high coupler forces. The results of the study indicate that the MRAC system significantly improves braking distance while maintaining better wheel/rail adhesion and coupler dynamics during braking. Furthermore, according to this study, the braking distance can be accurately estimated when MRAC is used. The robustness of the MRAC system with respect to different parameters is investigated, and the results show an acceptable robust response behavior.

A presente tese descreve as etapas de desenvolvimento de um equipamento (tribômetro) e metodologia de ensaio para caracterização do efeito isolado da temperatura sobre o atrito medido em materiais de fricção utilizados em freios veiculares. O projeto deste equipamento foi baseado nas funcionalidades e limitações encontradas nas principais máquinas e procedimentos de ensaio para freios automotivos. São apresentados e discutidos detalhes do projeto mecânico e de automação do tribômetro, bem como são levantadas suas incertezas de medição instrumentais e precisão. Além disso, é proposta uma nova metodologia de ensaio para caracterização do efeito isolado da temperatura sobre os resultados de atrito obtidos durante os testes. O projeto mecânico atual do tribômetro contempla recursos que contribuem para facilitar a operacionalidade do equipamento e, consequentemente, reduzir o tempo envolvido na etapa de preparação dos testes. São exemplos destes recursos um mecanismo de fuso e manivela, o qual é empregado para a regulagem do raio de deslizamento, e um dispositivo para troca rápida da amostra a partir do ajuste de um único parafuso. O atual projeto de automação do tribômetro é composto por circuitos de controle da carga, rotação, torque e temperatura, os quais operam em malha fechada. A incerteza instrumental do sistema de medição de atrito do tribômetro é igual a ±2,9% do valor nominal medido, considerando a faixa típica de aplicação da máquina. Em termos de precisão, verificou-se experimentalmente que o equipamento projetado apresenta uma repetitividade de ±0,013. O projeto de automação também contemplou a ligação do tribômetro a um aquecedor indutivo. O uso da referida tecnologia em conjunto com a metodologia de ensaio proposta na presente tese mostraram-se capazes de caracterizar de forma acelerada e independente o efeito da temperatura sobre o coeficiente de atrito obtido a partir de ensaios de frenagem executados no tribômetro. Complementa o estudo ainda o desenvolvimento de uma técnica para pós-processamento dos dados relativos aos ensaios executados no tribômetro segundo a metodologia proposta. A referida técnica mostrou-se uma maneira eficiente e relativamente simples de avaliar os efeitos simultâneos da carga e da temperatura sobre o atrito.

▼

In this research work, a variable braking force system is designed and applied to a motor cycle rear wheel to control the maximum braking force which is developed between the tyre and the ground, for reducing the stopping distance of the motor cycle and thereby improving the motor cycle safety and riders. In variable braking force system, the effective radius of the disc is varied by moving the position of the caliper along the radial direction over the disc of the braking system based on the pillion load on the motor cycle. Hence the maximum braking force developed between the ground and the tyre is controlled based on pillion load on the motor cycle if the friction is present between the tire and ground. In other words, the maximum traction capacity between the tyre- road system is utilized. A typical motor cycle is selected to accommodate the variable braking force system. The centre of gravity which is measured by adopting a suitable method is required to design the braking system of the motor cycle. An optimum brake disc radius is determined based on the pillion load and vehicle geometry of the typical motor cycle, keeping rider weight and hydraulic brake line pressure constant. Moreover, the effective disc radius is determined for the various loads which are acting on the pillion of the motorcycle. The motorcycle which is selected for implementing variable braking force system, has a drum brake. Since the drum brake is not suitable to vary the effective disc radius, it is replaced with disc brake that is available in the new model of the same motor cycle. The disc brake that is procured, needs to be modified to implement the variable braking force system. In the new disc brake, modification work is done on brake caliper and its holder, disc and wheel hub of the motor cycle for achieving the variable braking force. In that modification work caliper and its holder are designed in three different methods.

▼ Industrial robots are increasingly used within the manufacturing industry, especially in collaborative applications, where robots and operators are intended to work together in certain tasks. This collaboration needs to be safe, to ensure that an operator does not get injured in any way. One of several solutions to this is to use virtual safety zones, which limits the robots working range and area to operate within, and may be more flexible than physical fences. When the robot exceeds the allowed limit of the virtual safety zone, a control system that monitors the robot position, forces to robot to stop. Depending on the current speed and payload of the robot, the initialized stop has a braking distance until the robot has completely stopped. How far the separation distance between human and robot must be, is calculated using ISO-standard guidelines when doing risk assessments. To support affected personnel in their work, an investigation and experimentation of braking distances among several robots has been conducted. These testing experiments have been designed to simulate a collaborative operation which is an excessive risk in a robot cell. The tests have been performed with various speeds and payloads, for comparison between the robot models and for validation against already existing data. The difference with this study compared to existing ones is that several robot axis’ are used simultaneously in the testing movements, which is a benefit since a robot rarely operates with only one axis at a time. Main results of the performed tests are that the robot doesn’t obtain speeds over 2000 mm/s when axis 1 is not involved, before the virtual safety zone is reached. Axis 1 can generate the highest speeds overall, and is therefore a significant factor of the braking distance. The results and conclusions from this thesis states that these kinds of tests give useful information to the industry when it comes to safety separation distance and risk assessments. When applying the information in a correct way, the benefits are that a shorter safety separation distance can be used without compromising on safety. This leads to great advantages in robot cell design, because space is limited on the factory floor.
