摘　　要：由无源滤波器和有源电力滤波器(APF)串联构成的并联型混合有源滤波器(SHAPF)适用于高压大容量的谐波补偿场合。针对扰动较敏感的广泛性负载,提出了一种重复线性自抗扰控制(LADRC)方法。LADRC方法不依赖于被控对象精确的数学模型,且具有很强的抗干扰能力,提高系统鲁棒性。采用重复控制对LADRC方法进行补偿,消除周期性稳态误差,提高系统的稳态精度。仿真和实验结果证明了重复LADRC方法在谐波抑制方面的正确性和有效性。Parallel shunt hybrid active power filter（SHAPF） consisting of passive and active filters is suitable for high voltage and large capacity harmonic compensation occasion.For the load which is more sensitive to disturbance,a complex control method is presented,which including the repetitive control and the liner auto disturbance rejection contml（LADRC） method.LADRC is independent of system model, and in can resist interference effectively.LADRC is applied to eliminate periodic steady-state error and improve the compensation accuracy.The simulation and experimental results have demonstrated the validity and efficiency of the LADRC method for harmonic suppression.
