摘要
有源电力滤波器(APF)的控制包括补偿电流控制以及直流侧电容电压的控制两部分,在对空间电压矢量脉宽调制(PWM)控制方法及直流侧电压控制的基本原理研究的基础上进行仿真,仿真结果表明基于空间电压矢量PWM技术的补偿电流控制方法的补偿效果较理想,为进一步提高基于空间矢量控制策略的补偿效果,在闭环控制的基础上,引入模糊自适应比例积分(PI)控制器,减小了补偿电流的跟踪误差,并降低了补偿后电源侧电流的畸变率。实验结果也验证了所设计控制方法的有效性。
The control of active power filter （APF） includes two parts such as the compensation current control and direct current side capacitor voltage control.Basing on the research of the basic principle of the space voltage vector pulse width modulation （PWM） control method and the direct current side voltage control, the simulation is made, the simulation results show that the effect of the compensation current control based on voltage space vector PWM tech- nology method is ideal.In order to further enhance the compensation effect of space vector control strategy the fuzzy adaptive proportional integral（PI） controller is introduced based on closed-loop control and this reduces the track- ing error and current distortion of the supply side.Experimental results also verify the effectiveness of the control method designed.
