一种电压发生器的双闭环控制系统研究

Research on Double Closed Loop Control System of Voltage Generator

基于一种用来模拟电网电压幅值、频率波动的三相电压发生器拓扑,根据其拓扑结构原理和控制系统的设计,提出了一种新型的双闭环控制系统方法(电压外环、电流内环配合电压前馈的控制策略)。最后,通过MATLAB/Simulink仿真和试验,验证了该控制策略的有效性。

Based on a three-phase voltage generator topology used to simulate the voltage amplitude and frequency fluctuation of the power grid, according to its topology structure principle and control system design, a new double closed-loop control system method(the control strategy of voltage outer loop and current inner loop combined with voltage feed forward) is proposed. The effectiveness of the control strategy is verified by MATLAB/Simulink simulation and experiment.
