| 摘 要： | 针对有源电力滤波器存在滤波效果不够理想这一问题。根据系统的参考信号是周期变化的特点．提出了一种基于PI型学习律的迭代学习控制算法。通过实施遗忘因子学习律增强系统鲁棒性的同时。引入了在最优目标下选择模糊参考电流误差的D型学习律前馈环节。并且利用PSIM软件对所提出方法和传统的滞环控制方法进行了仿真实验。从动态响应和控制精度两个方面做了比较。验证了所提出方法的可行性。

| Abstract: | The performance of the active power filter with traditional controller is not good.According to the periodic characteristic of the reference signal,this paper proposes a PI-type iterative learning control algorithm,by means of using a forgetting factor to enhance systemic robustness,and at the same time importing a D-type learning law feed forward based fuzzy-inferring referenced current error under the optimal object.Finally,the feasibility of the new control method is verified by simulation analysis with PSIM software and comparison with conventional hysteresis control in terms of dynamic response and control accuracy. |
