| 摘 要： | 针对线性时变系统的轨迹跟踪控制问题,提出一种带参考批次的迭代学习控制算法,并给出了算法的收敛性分析.该迭代学习控制算法不需要事先了解线性时变对象的太多知识,而是将当前批次输入轨迹的较小变化所引起的输出轨迹作为参考批次,并以当前批次与参考批次的输入变化与对应的输出变化之比作为学习律,从而实现目标轨迹的跟踪.以一个典型的线性时变系统为例进行仿真分析,验证了所提出算法的有效性.

| Abstract: | For the trajectory tracking control of linear time-variant system,an iterative learning control method is presented and the convergence proof is given.This method does not need detailed knowledge of the system.However,a reference batch is designed,in which some small change of input trajectory in the current batch is applied to the system.Then its output trajectory is obtained.The ratio of the input change and corresponding output change in the current and reference batch is used as the gain in the learning... |
