摘　　要：针对传统UPS主逆变器采用PID控制方法实现系统反应的快速性,而稳态特性不足的缺点。提出一种基于瞬时值反馈控制和重复控制的新型逆变电源控制方案,利用重复控制改善了系统的稳态特性。利用瞬时值反馈控制改善了系统的动态特性。通过PSIM9.0软件仿真分析和试验结果表明,本控制方案获得了良好的稳态和动态特性。Aiming at the shortcoming that the traditional UPS inverter adopts PID control method to achieve system＇s fast response, and is lack of steady characteristics, a new control scheme for inverter based on instantaneous feedback control and repetitive control is proposed, it adopts repeated control to improve the system＇s steady characteristics and utilizes instantaneous feedback control to improve the dynamic behavior of the system. The simulation analysis and experiment results by using PSIM9.0 software show that this control scheme has good steady and dynamic characteristics.
