摘　　要：对于具有随机时延的一类离散系统的滤波器型迭代学习控制,采用满足Bernoulli分布的二进制序列来描述数据传输的随机时延,利用线性矩阵不等式方法设计具有随机时延的l2-l∞滤波器.给出了滤波误差系统均方指数稳定且具有给定的l2-l∞性能的充分条件,分析了滤波器型迭代学习控制收敛的充分条件.仿真实例说明了该设计方法的有效性.The problem of the systems with random delays iterative learning control based on l2-l∞, filter is solved for stochastic discrete-ime The random delays are described by using a binary switching sequence satisfying a conditional probability distribution. Filters are obtained such that the filter error systems are exponentially meansquare stable and guarantee a prescribed energy-to-peak disturbance attenuation level in term of linear matrix inequalities （LMIs）. The iterative learning control based on the filter is designed. The simulation results show the effectiveness of the proposed design approach.
