摘　　要：根据重复控制的无静态误差跟踪性和无差拍控制快速响应及控制精度高的特性,在UPS逆变器控制系统中,提出了基于重复与无差拍控制复合控制策略。重复控制可以很好地消除周期性干扰,无差拍控制以减小当系统受到较大扰动时出现的超调和振荡,改善系统的动态性能。仿真表明,基于重复与无差拍控制复合控制策略具有瞬时响应快、精度高、THD小等特点。A composite control strategy is proposed based on the repetitive control and deadbeat control in the ups inverter control system, according to the features of the non - static error track of repetitive control and the deadbeat control＇s fast response and high precision control. Repetitive control can be very good to eliminate periodic disturbance, and deadbeat control to reduce the overshoot and oscillation, when the system is subject to greater disturbance, that can improve the dynamic performance of the system. Simulation results show that it has a fast transient response, high accuracy, THD and other small features.
