摘要：
Aiming at the disadvantage of the conventional PI controller of three-phase VIENNA rectifier, which has poor input AC static error and anti-load disturbance dynamic performance, a load current feed-forward proportional resonant(PR) control algorithm for VIENNA rectifier was proposed. PR controller is used to eliminate the phase difference between the input voltage and current effectively as well as realize the tracking without static error. The load current feed-forward compensation link is embedded outside the current closed loop, and the load disturbance information is directly acted on the current through the feed-forward link, which improves the dynamic adjustment time of anti-load disturbance and enhances the system immunity. The performance of the proposed method was compared with that of traditional PI control strategy. The test results show that the proposed algorithm can effectively enhance the dynamic performance and input power factor under load disturbance operation condition. © 2019, Harbin University of Science and Technology Publication.
