中文摘要
      针对有限时间区间内执行重复控制任务的线性连续切换系统, 考虑基于迭代学习的跟踪控制问题. 假设线性切换系统的切换率在时间域内是任意的, 提出该类系统的D型迭代学习控制算法. 理论分析表明, 当学习增益矩阵满足一定的条件时, D型迭代学习控制算法可以保证切换系统的实际输出在整个运行区间上一致收敛于期望输出, 实现完全跟踪控制. 数值仿真进一步验证了方法的有效性.
英文摘要
      The problem of iterative learning control for a class of linear continuous-time switched systems with arbitrary switched rules is considered. It is assumed that the considered switched systems are operated during a finite time interval repetitively, and then the iterative learning control scheme can be introduced. It is also shown that under some given conditions, the D-type iterative learning control law can guarantee the asymptotic convergence of the output error between the desired output and the actual output for the entire time interval through the iterative learning process. And then an example is given to illustrate the effectiveness of the proposed approach.
