摘　　要：针对常规PID控制器由于受采样频率等因素影响而难以获得满意的控制效果的问题,研究了并联型有源电力滤波器的分数阶微积分控制策略,采用改进Oustaloup算法求解分数阶微积分。Matlab仿真结果表明,该控制策略比常规PID控制策略能更好地将直流侧电压稳定在设定值;得到的网侧电流更平滑,更接近于正弦波;在补偿瞬间的冲击电流更小,补偿跟踪电流可以很好地跟踪指令电流。In view of problem that conventional PID controller is difficult to obtain satisfactory control effect due to sampling frequency and other factors, a control strategy of fractional order calculus for shunt active power filter using improved Oustaloup algorithm for solving fractional calculus was studied. The Matlab simulation results show that the control strategy can better stabilize DC side voltage to set point, and can get smoother grid current which is closer to sine wave than conventional PID control strategy. Impact current at the compensation instant is small, and tracking and compensation current can track command current effectively.
