| 摘 要： | 针对一类时不变或慢时变的离散时间非线性系统,首先在线性鲁棒自适应控制的基础上,给出了系统有界输入-有界输出的稳定性证明,并得到了系统有界输入-有界输出稳定的充分条件;继而将其引入到多模型切换控制中,经证明该条件可以保证间接多模型自适应切换控制的稳定,较好的兼顾了系统的稳定性和瞬态响应,从而为间接多模型自适应控制器的设计提供了理论依据.

| Abstract: | In this paper,for a class of fixed or slowly time-varying nonlinear discrete time systems,based on the linear robust adaptive control,it proved that the system is bounded-input and bounded-output(BIBO).Simultaneously got sufficient condition which guarantee the system BIBO;then this sufficient condition is introduced into multiple model control,it has proved that this sufficient condition can guarantee the stability of indirect multiple model adaptive switching control.By using a switching scheme,it is demonstrated that improved performance and stability can be simultaneously achieved.Thus it provides theoretic basis for the design of indirect multiple model adaptive controllers. |
