摘要
文章通过构造Lyapunov函数,利用线性矩阵不等式,对一类分布参数切换系统给出了保成本控制存在的充分条件。该条件用一组线性矩阵不等式表示,将分布参数切换系统的保成本控制问题转化为一组线性矩阵不等式的可行解问题,可借助Matlab中线性矩阵不等式工具箱求解,且结论容易检验和应用。最后通过数值算例,验证所提出设计方法的有效性。
By constructing Lyapunov functions and employing linear matrix inequality(LMI),a number of sufficient conditions of the existence of guaranteed cost controller for a class of distributed parameter switched systems(DPSS) are derived.These conditions are described by a group of LMIs,so the design of the guaranteed cost controllers of DPSS is transformed into the feasible solution problem of some certain LMIs.The controllers can be efficiently solved by means of Matlab LMI toolbox,then the criteria can be checked and the method can be applied easily.Finally,a numerical example shows the validity of the proposed design method.
