基于PID和重复控制的三相四桥臂逆变器的研究OA北大核心CSTPCD
The Research of Three-phase Four-leg Inverter Based on PID and Repetitive Control
在三相四桥臂逆变器被解耦成三个单相逆变器的基础上，提出了一种PID与重复控制相结合的控制策略。首先采用开关周期平均法和旋转坐标变换，建立旋转坐标系下的平均大信号模型，在此模型的基础上设计简单明了的PID控制器。其次对整个系统进行重复控制器的设计，居于外环的重复控制可以减小周期性扰动产生的畸变，提高系统的稳态性能。仿真结果表明，在不平衡负载和非线性负载情况下，逆变器都能够保持完好的电压输出特性和良好的动态特性。
A control strategy with PID and repetitive control was proposed, which was based on the three-phase four-leg inverter being decoupled into three single-phase inverters. Firstly, the switch cycle average method and the rotary coordinate transformation were used to establish average large signal model in rota-ting coordinate system. In addition, a simple PID controller could be designed based on this model. Then , a repetitive controller was applied to the who…查看全部>>
