摘要
对一类同时具有状态时滞和输入时滞的不确定离散时滞系统,提出保性能状态时滞反馈控制律的设计问题。结合一个二次型性能指标,基于Lyapunov函数和线性矩阵不等式处理方法,推出状态时滞反馈保性能控制律存在的条件,并用线性矩阵不等式的可行解给出保性能控制律的构造方法。最后给出一个仿真例子证明该方法的有效性。
For uncertain discrete-Time-delay systems with both state and input delays,this paper addresses the problem of designing an guaranteed cost state feedback time-delay controller.Together with a given quadratic performance index,a sufficient condition for the existence of guaranteed cost state feedback timedelay control law is derived on basis of a Lyapunov function and Linear matrix inequalities.Furthermore,we give the conformation approach for guaranteed cost control law using the feasible solution of Linear matrix inequalities.Finally,an example is given to demonstrate the efficiency of the proposed approach.
