摘　　要：针对传统重复控制器存在固有延时特性,动态性能较差的问题,采用一种基于比例控制和快速重复控制的改进型控制策略。比例控制器增强VIENNA整流器的稳定性并提升一定的响应速度,快速重复控制器提高控制频率,减小固有延时。对系统的稳定条件、Q(z)滤波器的设计、控制器参数设计等方面做了详细的分析和计算。仿真和实验结果表明:所提出的控制策略可以有效改善传统重复控制器的延迟问题,提高系统的动态响应能力。Aiming at the problems of inherent delay and poor dynamic performance of traditional repetitive controller,an improved control strategy based on proportional control and fast repetitive control is adopted.The dynamic performance of the system is improved by parallel connection of proportional controller and fast repetitive controller.The proportional controller enhances the stability of VIEN-NA rectifier and improves response speed,and the fast repetitive controller improves the control frequency,reduces the inherent delay.The stability conditions of the system,the design of Q(z)filter and the design of controller parameters are analyzed and calculated in detail.The simulation and experimental results show that the proposed control strategy can effectively improve the delay problem of tra-ditional repetitive controller and improve the dynamic response ability of the system.
