摘　　要：设计了一种含有扰动反馈的双环PI控制系统,无需考虑扰动的实际模型,对所有非线性扰动叠加和的估测值前馈补偿,能有效抑制前向通路中扰动的影响。通过仿真和实验比较加入扰动反馈前后的电网电流波形,验证了该方法对改善输出电流波形质量、提高系统稳态误差的可行性和有效性。A double-loop PI control system containing a disturbance feedback is designed. Regardless of the actual model of the disturbance,superimposed all non-linear disturbance and feed-forward the estimated value to compensate,which can effectively suppress the disturbance of the forward path. Comparing the difference of grid current waveform between when control system contain disturbance feedback and not through the simulation and experiment,it verified that the method is feasible and effective to improve the output current waveform quality and the system steady-state error.
