|
摘要
针对电力有源滤波器由于其检测精度、指令电流计算时延和输入滤波器的相移等因素而造成的滤波效果性能下降的问题,采用了一种结合模糊控制技术和递推积分PI控制于一体的模糊递推积分PI控制方法。该方法可以实现较好的滤波性能,并且可以提高系统的动态响应性能,降低稳态误差。对所提出的方法进行了仿真验证,证明了该方法的可行性。
For the performance decrease of the active power filter(APF) due to the influence of detection accuracy,time delay of instruction current calculation and phase shift of input filter, a kind of fuzzy recursive integral PI control combining fuzzy control technology and recursive integral PI control technology was proposed. The proposed method can realize good filter, improve the system's dynamic response performance and lower static error. The simulation verification was conducted, confirming the validity of the proposed method.
