| 摘 要： | 针对一类参数未知非线性的迭代学习控制问题提出了一种开闭环PID型迭代学习控制律,这种迭代学习律同时利用了系统当前的跟踪误差和前次迭代控制的跟踪误差修正控制作用,给出了迭代学习控制算法收敛的充分性条件.分析表明,所给出的迭代学习控制律推广了现有的结果.

| Abstract: | In this paper,an open-closed loop PID-type iterative learning control scheme for a class of nonlinear time-varying system with unknown parameters is proposed.In this scheme,the system current tracking error and previous tracking error are both used to update control input meanwhile.Then sufficient conditions for the convergence of the proposed learning scheme are given.The conditions are more general than the known results. |
