Design of Multi-functional Grid-connected Inverter Based on Modified Repetitive Control Algorithm
摘要
Abstract
The multi-functional grid-connected inverter can improve power quality while used to transmit active power.To make the inner loop controller track reference current fast and accurately, a new design method of inner loop controller based on the modified repetitive control algorithm is proposed.The modified repetitive controller is composed of a proportional controller and a traditional repetitive controller connected in parallel, and an equivalent controlled object is used for analyzing the stability, steady state error and dynamic performance of the inner loop control system and designing the parameters of the modified repetitive controller.Finally, simulations and experiment results show that the proposed inner loop controller can track reference current fast and accurately and multi-functional grid-connected inverter based on the modified repetitive control algorithm has an excellent ability to enhance power quality.关键词
