摘　　要：针对模糊线性自抗扰控制的缺点,提出变论域模糊线性自抗扰控制。该控制可根据误差以及误差变化率调整模糊控制的输入输出论域。因此,所提出的控制方法可在不增加模糊规则数目,不改变隶属度函数的情况下,提高模糊线性自抗扰控制的稳态精度。仿真结果和实验结果表明:相对于有源电力滤波器(APF)直流侧电压的模糊线性自抗扰控制,所提出的变论域模糊线性自抗扰控制具有更快的响应速度,更高的稳态精度以及更小的总谐波失真(THD)。Aiming at the shortcomings of fuzzy linear active disturbance rejection control,a variable universe fuzzy linear active disturbance rejection control is proposed.Input-output domain of fuzzy control can be adjusted according to the error and the error change rate.The proposed control method can improve the steady-state accuracy of fuzzy linear active disturbance rejection control without increasing the number of fuzzy rules and changing the membership degree of the function.Simulation and experimental results show that compared with the fuzzy linear active disturbance rejection control of active power filter(APF) DC side voltage,the proposed variable universe fuzzy linear active disturbance rejection control has faster response speed,higher steady-state accuracy and less total harmonic distortion(THD).
