1. Liu, Yuqian. Control and Navigation of Autonomous Underwater Vehicles.

Degree: MS, Mechanical Engineering, 2014, University of Connecticut

This thesis presents an efficient attitude control design, which combined L1 adaptive control and backstepping control together. Based on this attitude controller, a design of autopilot is also proposed for the fixed-point navigation scenario. An advanced design of Autonomous Underwater Vehicles (AUV) driven by four water pumps is reviewed first. With different power distribution of these pumps, the AUV could provide the capability for propulsion and maneuver to achieve the desired motion. Based on this prototype, the modeling analysis, including rigid body dynamics, actuator dynamics, force and moment generation, is presented. In view of well study of the nonlinear AUV dynamic model, the design of the attitude control is proposed. In Euler-angle representation, kinematics and dynamics of the attitude are in the strict feedback form. The uncertainties only in dynamics are considered, which come from modeling uncertainties, actuator dynamics and external disturbance. By using backstepping as the baseline controller and bringing adaption for dynamics problem, this control strategy for attitude is developed. For uncontrollable channel, the self stability is also analyzed. Simulations are used to demonstrate the performance of this controller in comparison to a conventional backstepping controller in this thesis. Further, based on the fixed-point navigation, an autopilot design for this AUV is also presented. Conclusions and future work for AUV topics were presented at the end of this thesis. Advisors/Committee Members: Prof. Junhong Cui, Prof. Jiong Tang, Prof. Chengyu Cao.

2. Cremins, Matthew D. Fault Detection in Railway Track Using Piezoelectric Impedance.

Degree: MS, Mechanical Engineering, 2014, University of Connecticut

In this thesis, piezoelectric transducers are incorporated in an impedance-based damage detection approach for railway track health monitoring. The impedance-based damage detection approach utilizes the direct relationship between the mechanical impedance of the track and electrical impedance of the piezoelectric transducer bonded. The effect of damage is shown in the change of a healthy impedance curve to an altered, damaged curve. Using a normalized relative difference outlier analysis, the occurrences of various damages on the track are determined. Furthermore, the integration of inductive circuitry with the piezoelectric transducer is found to be able to considerably increase overall damage detection sensitivity.

3. Felemban, Haitham B. Continuous Polynomial Adaptive Estimator for Nonlinearly Parameterized Systems.

Degree: MS, Mechanical Engineering, 2014, University of Connecticut

This the sis present the continuous polynomial adaptive estimator CPAE which estimates a nonlinear parameter in nonlinearly parametrized NLP system. It combines the multiple region law with the companion adaptive system presented in [1] to come up with the CPAE. Stability is discussed and general definition of persistence of excitation PE condition is proposed for parameter convergence using the CPAE. As an application, the CPAE was successfully used to estimate the airspeed in presence of airspeed sensor failure on a developed academic aircraft model. As part of Loss of Control Prevention through adaptive reconfiguration project supported by NASA, the IMU theory method, which estimates airspeed using data from the inertial measurement unit IMU and the global positioning system GPS, is presented and applied on the generic transport model GTM. Conclusions and future work for aforementioned topics were presented at the end of this thesis. Advisors/Committee Members: Prof. Robert Gao and Prof. Jiong Tang, Prof. Chengyu Cao.
