摘要：In this paper, a novel optimized switching repetitive control (OSRC) scheme is developed and applied to a constant-voltage constant-frequency pulse width modulation inverter to enhance the stability and tracking performance with low sampling frequency. In OSRC, a switching integral phase lead compensator is applied to enlarge the stability margin, which is impaired by the phase lag of the inverter system. With the optimized switching strategy, the stable region can be much wider, which means that a larger robust filter Q can be applied to reduce the tracking error. The stability analysis and optimized design procedure are also given. Comparative experiments in different load situations are performed to demonstrate the validity of the proposed scheme.
