基于PI控制的交流电子负载内环电流控制的改进
Improved inner current control of AC electronic load based on PI control
The AC electronic load has the weaknesses of poor anti disturbance capacity when using PI control. This paper analyzes the main circuit structure of AC electronic load and its control method,presenting a combined control method to improve the PI control.This method keeps the tracking speed of the inner loop current controller and improve the anti-interference ability of the system , then according to type system to determine the parameters of PI controller. . The research is proved to be effective by simulation.
