| 摘 要： | 针对传统比例-积分-微分(proportional integral differential,PID)控制器不能实现具有周期性特点的电网谐波电流无稳态误差跟踪的特点,提出了一种新的PID型迭代学习控制算法,同时建立了一种模糊规则并利用模糊推理对PID控制器的比例、积分和微分系数进行在线修正,实现对系统的无差控制。在此基础上,为提高系统的响应速度,将PID迭代学习控制与滑模变结构控制有机结合,提出了复合型变结构控制方法。该方法具有响应速度快、控制精度高、易于实现的特点。仿真和实验结果证明了该控制方法的可行性和有效性,效果优于传统PID控制。

| Abstract: | It is not ensured for traditional proportional integral differential(PID) controller to trace non-steady-state error of periodical signals.According to the feature that the reference signal of filtering system is such a periodical signal that is superposed by multi harmonics with different frequencies,a novel iterative learning control algorithm for PID controller is proposed and a set of fuzzy rules is established;on this basis the on-line correction of proportional coefficient,integral coefficient and dif... |
