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.
