Abstract It is well known that the system performance of an induction motor with indirect field oriented control degrades under the variation of rotor resistance and in the presence of external load disturbance, and the shortage of the conventional robust control approaches in considering robust stability and robust performance simultaneously is introduced briefly. In order to solve these problems, Youla parameterization based two-degree-of-freedom controller using robust design method is studied, the feedback controller is design using H_∞ mixed sensitivity to guarantee the robust stability and performance of feedback closed loop. The H₂ optimization based feedforward controller is design to obtain the robust performance of tracking even under model error. Simulation results demonstrate that the proposed approaches can improve the system performance under plant parameter variation and external disturbance.
