中文摘要：

针对离散线性时不变系统,研究了参数区间不确定迭代学习控制系统（IILC）的单调收敛性条件,并针对常见的离散PD型ILC算法,给出了在l∞范数意义下区间不确定迭代学习控制系统单调收敛性的判断方法,数字仿真结果证明了其有效性。

英文摘要：

Monotonic convergence of interval iterative learning control for discrete linear time invariant system with interval uncertainty was discussed.For commonly used algorithms of discrete PD iterative learning control,the monotonic convergence condition in the l∞-norm topology was checked specially.Simulation results show that the approach is effective.
