Abstract

In order to solve the problem of classic control methods in slow transient response and low anti-interference capacity, this paper proposed a dual closed-loop control scheme based on sliding mode(SM) and proportional-integral(PI) control for a three-phase rectifier. In this work, the error between id, iq and their desired value were treated as the states of the sliding mode surface, considering the control objectives of power factor and output voltage, which improved the stability and robust performance; besides, a double power reaching law was applied in the controller, which improved the dynamic performance, as well as restraining the chatter. Finally, the proposed strategy was tested in simulation and experiment compared with dual close-loop PI-PI scheme.
