Abstract
A control strategy with PID and repetitive control was proposed, which was based on the three-phase four-leg inverter being decoupled into three single-phase inverters. Firstly, the switch cycle average method and the rotary coordinate transformation were used to establish average large signal model in rota-ting coordinate system. In addition, a simple PID controller could be designed based on this model. Then , a repetitive controller was applied to the whole system and the repetitive controller in outer loop re-duced the distortion generated by periodic disturbance as well as enhanced steady state performance of the system. The results showed that output voltage characteristics and dynamic state performance of the in-verter were excellent under unbalanced load and nonlinear load conditions.关键词
