摘　　要：提出基于重复控制的积分-比例积分(IPI)控制策略,其将比例积分(PI)控制与重复控制并联,并对重复控制器进行改进,使IPI控制器实现无静差控制,有效提高系统的控制精度,实现大功率非线性负载时较好的控制效果。改进的重复控制器决定系统的稳态精度,PI控制器决定系统的动态响应速度。仿真和实验结果验证了所提控制策略在谐波控制及系统稳定性方面的有效性和可靠性。The IPI（Integrate and Proportion Integrate） control strategy based on repetitive control is proposed for large-capacity APF,which executes PI control and repetitive control in parallel. The repetitive controller is improved to realize the IPI controller with zero steady-state error. The control accuracy of system is effectively improved to achieve better control performance for high-power non-linear load. The improved repetition controller determines the steady-state accuracy of system and the PI controller determines the dynamic response speed of system. Simulative and experimental results show the efficiency and reliability of the proposed control strategy in harmonic control and system stability.
