摘　　要：研究含有不确定参数切换系统的自适应镇定问题.为子系统分别设计自适应控制器,通过设计依赖于切换信号的子适应律,避免了由共用状态引起的各子适应律之间的耦合问题.采用多Lyapunov函数设计系统控制器,不要求子系统的确定性等价镇定控制器存在,通过切换律的设计可以保证闭环切换系统的渐近稳定性.The adaptive stabilization problem is studied for switched systems with uncertain parame- ters. Sub-adaptive controllers are designed respectively for the subsystems of the switched system. Adap- tive laws are made dependant on the switching signal in order to avoid the coupling between the adaptive laws which is caused by sharing a common state. Multiple Lyapunov functions method is used to design the controllers. There is no need for subsystems to have certain equivalent controllers because a properly de- signed switching law can ensure the asymptotical stability of the closed-loop switched system.
