针对交流电子负载内环电流PI控制存在抗干扰能力差的缺点，在分析交流电子负载的主电路结构及其控制方法的基础上，提出将扰动电压前馈的复合控制方法，在保持内环电流PI控制器跟踪速度的前提下，提高了系统的抗干扰能力，并通过对交流电子负载的建模，按照典型型系统整定方法，确定了PI控制器中参数的大小，仿真表明，该方法能够很好的抑制电压侧带来的扰动，实现交流电子负载负载模拟的功能。

The AC electronic load has the weaknesses of poor anti-disturbance performance when using inner current PI control.This paper analyzes the main circuit structure of AC electronic load and its control method, presenting a combined control method to feed-forward the disturbance voltage.This method keeps the tracking speed of the inner loop current PI controller and improves the anti-interference ability of the system.And then, through the AC electron-ic load modeling, and according to setting method of typicaltype system, the parameters of PI controller are deter-mined.The research is proved to be effective by simulation.
