摘　　要：电力有源滤波器控制技术中,针对传统PI控制方式不能完全跟踪周期变化的参考电流这一问题,引入广义积分控制算法来降低系统的稳态误差,并利用PSIM进行了仿真验证。为提高系统的动态性能,提出将广义积分控制算法与改进的滞环控制有机结合,构成了一种新型复合型电流滞环控制方法,并通过仿真比较说明了方法的优越性。在实验中,为减小计算量,提出了广义积分迭代算法,验证了仿真分析结果和实验结果的一致性。所提方法具有计算量小、容易实现的特点,具有一定的实用价值。Because the traditional PI control method can＇t completely track the periodic reference signal of current for APF control system,a control algorithm of generalized integrator is used to eliminate the steady error,and PSIM simulation is done to prove the method.And to promote the dynamic performance of the system,a new complex hysteresis controller is proposed based on generalized integrators and improved hysteresis control method.Simulation results prove the superiority of proposed method.An iterative control algorithm is used to reduce calculation amount in experiment,and confirm the identity between the simulation and the experiment.The new method is simple,easy to apply,and possesses some practical values.
