摘要
基于UPS逆变器的重复控制技术,通过内模原理进行了介绍,对重复控制器的稳定性进行了研究,并通过重复控制策略使逆变电源输出电压波形质量得到改善,提高了系统的静态性能。仿真和实验均验证了该方案的可行性。
The inner modle theory based on the repetitive control strategy used in inverter system is proposed. The stability of the repetitive controller is analysised. The repetitive control is used to reduce voltage distortion under nonlinear loads and also to improve the static stead performance. The simulation and experimental results are all reported, confirming the validity of the proposed control technique.
