Abstract : A high performance motor drive requires fast step-tracking response with acceptable overshoot, minimum speed-dip and restore-time following a step load change, and zero steady-state error in the command tracking and load regulation. In this paper, a comparative study is carried out between two output-feedback control techniques to achieve a high performance induction motor. The first, named Discrete-Time Dynamic Programming (DTDP) output feedback, uses historical data from the controlled inputs and outputs of the motor and an optimization technique, dynamic programming algorithm, to obtain an optimum design of the needed constant output feedback gain matrix. In the last, named Linear Matrix Inequalities (LMI) output-feedback, the reduction of the disturbance on the motor speed is done through the minimization of the H-infinity (H) norm using Linear Matrix Inequality. The design procedure is based on the linearization of the motor nonlinear current-model around a selected operating point. The system performance of the motor equipped with DTDP and LMI controllers is analyzed using diverse tests namely, load disturbance (regulation and tracking) and parameters variation. For completeness, the performance of a conventional Proportional-Integral (PI) controller are also included for comparison purposes. The results are very encouraging to pursue further this study.
