摘要

针对单相并网逆变器系统

给出了一种重复控制器的补偿器简化设计方案。重复控制虽能够保证系统稳态时的输出精度

但是其系统调节的实时性差。为了克服重复控制器动态响应差的缺点

采用了一种基于PI控制和重复控制的复合式控制方法

既保证系统的稳态输出特性

又提高了系统的动态性能。仿真结果验证了复合式控制方法的正确性。

Abstract

A simplified design of taking a PI controller as the compensator of a repetitive controller is proposed for single-phase grid-connecting converter system. The repetitive controller can ensure the output accuracy when system is in steady state

but its dynamic response is not fast enough. To overcome this weakness

a composite control scheme based on PI and repetitive controllers is presented

which can ensure the steady-state output characteristics of the system

and improve its dynamic properties. Simulation verifies the correctness of the composite control scheme.
