通过构造参数相关的李雅普诺夫函数 ,利用S procedure方法研究一类具有参数不确定性和状态滞后的线性动态系统 ,得到了这类不确定时滞系统存在保成本控制器的充分条件
By constructing the Lyapunov function with parameters, a class of linear dynamic system with parametric uncertainty and state lag is studied by using S procedure method. The sufficient conditions for the existence of guaranteed cost controller for this kind of uncertain time-delay systems are obtained.
