Abstract :
This paper describes a new method for the high performance speed control of an induction motor drive system based on field-oriented control. Since the performance of the closed-loop controlled machines is influenced by load torque and parameter variations in wide speed range operation, a model reference robust control (MRRC) scheme to reduce load perturbations is employed. To compensate motor parameters variations, an algorithm to estimate the rotor time constant, based on stator quantities is used. To simplify the design of the MRRC scheme without performance degradation, a simplified model is obtained by using ARMAX identification techniques. The control performance is analyzed by simulation, considering the constant changes and load perturbations and the obtained simulation results are presented
