摘要
PWM整流器在d-q旋转坐标系的数学模型中,有功电流与无功电流之间存在耦合,给控制带来困难。本文介绍一种基于输入输出反馈的电流解耦控制策略,使系统获得良好的线性控制特性。仿真结果表明,提出的方法具有优良的解耦性能。
In the mathematical model of PWM rectifier in d-q synchronous reference frame, there is cross coupling between active and reactive components of the line current, which is difficult to control. This paper introduces a current decoupled control strategy based on input-output variable feedback that achieves good property for linear control. Simulation results show that the proposed method has favorable performance for current decoupled.
