| 摘 要： | 利用驻留时间法和 Gronwall-Bellman不等式研究了一类切换系统的输入一状态稳定性分析与优化控制问题.在保证切换系统输入-状态稳定的前提下,将切换时刻和切换次数约束条件转化为线性约束,提出了一种新的切换系统优化问题目标函数的形式.与已有的方法相比,该方法无需引入新的状态变量,无需同时满足构造输入-状态稳定控制李亚普诺夫函数和所有子系统都是输入-状态稳定的条件,为控制器的优化设计提供了便利.最后,通过算例仿真证实了文中所提方法的可行性.

| Abstract: | Based on the dwell-time approach and Gronwall-Bellman's inequality,a new approach to input-to-state stability and optimal control problems for a class of switched systems is presented.Under the condition that input-to-state of switched system is stable,the constraint conditions on switching instants and switched number are transformed into linear form.A new form of objective function is constructed for switched system optimal problem.Compared with the existing methods,the proposed method does not employ new... |
