Abstract :
In this paper, the robustness stability and performance of robust repetitive control scheme is analyzed and synthesized by the structured singular value theory. A linear phase lead is introduced to improve the performance of robust repetitive control system. It compensates the phase lag of feedback control system and widens the cutoff frequency of Q filter. The periodic disturbance rejection performance of system is improved. Experiment results of a PWM converter system are presented to demonstrate the efficiency of the proposed approach
