(1)Real-time Implementation of Sensorless Nonlinear Controller for Induction Motor:

•Develop an enhanced FOC based nonlinear tracking controller for three phase induction motor through exploring feed-forward techniques. Develop an exponential stable dynamic flux estimator to provide accurate flux information for control design. Develop a third order Butterworth filter is designed to remove noise signal.

•Write C program to implement the developed FOC controller and flux estimator for three-phase induction motor manufactured by Baldor Electric Co. Two AE Techron LVC-2016 dual channel linear amplifiers are used to drive the motor. Two DAQ cards are used to obtain voltage, current and position signal. Another DAQ card is used to output desired three voltage signal.

•The Runga-Kutta algorithm is utilized to implement the developed controller instead of traditional bi-linear transformation to increase the accuracy of the discrete control law.

(2)Adaptive Tracking Control of Electronic Throttle System:

•Develop an observer-based adaptive tracking control algorithm for electronic throttle system without current measurement in DC motor.

•Develop a dual-loop PID based tracking control algorithm for electronic throttle system without current measurement in DC motor.

•Both strategy does not require accurate knowledge of system parameters and only requires position feedback signal. The controller is proved to be robust to both sensor noise and system uncertainty.

•Demonstrated the two proposed control algorithms through discrete implementation of control law in a high-fidelity continuous time electronic throttle body in Matlab/Simulink environment.

(3)On-line optimal energy management of battery-array system:

•Develop an on-line optimal energy management algorithm which can extend the life of battery array through model predictive control method. Both state constraints and input constraints are addressed.

•The developed algorithm is robust and tolerant to partial system failure.

(4)Advanced control design for power electronics load system

•Design a feedback plus feed-forward control strategy for a LCL filter based power electronics emulation system.

•The proposed controller is able to control desired current drawn from the grid under grid voltage changes. The grid disturbance is compensated within large frequency range.

(5) Teaching Assistant: EE3064: Feedback Control (Undergraduate Level), Spring, 2009

•Responsible for 1 hour lecture and supervision of 3 hour laboratory where junior and senior undergraduate students design and implement standard feedback control algorithm including PID, Lead/Lag compensator and digital filter to control DC motor using C language and DAQ card.

•Guide the students to use standard lab instruments including signal generator, Multimeter, Oscilloscope, etc.

•Responsible for grading of the report, code and lab final.
