基于重复控制策略的高性能逆变器控制器的设计

The Design of a High Performance Inverter Controller Based on the Repetitive Control

介绍了一种基于重复控制策略的高性能逆变器控制器,利用瞬时值反馈控制提高系统的动态性能,利用重复控制抑制非线性负载条件下的电压波形畸变,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控制器能实现高性能的输出特性。

The inverter controller proposed in this paper is based on repetitive control and instantaneous feedback control. Instantaneous feedback control is used to reduce fundamental component disturbance and to improve the dynamic response process of the system; Repetitive control is used to reduce voltage distortion under nonlinear loads and also to improve the static steady performance. Simulation and experimental results are all reported, confirming the validity of the proposed control technique.
