摘要
针对一类状态和控制输入同时存在不确定性的具有时变的时滞系统,使用线性矩阵不等式方法研究了其H∞反馈控制器的分析与设计。给出系统具有H∞性能一个线性矩阵不等式(LMI)条件,并通过建立受条件约束的线性矩阵不等式的描述,给出系统的一个-次优状态反馈H∞控制律的设计方法。最后用一个算例验证该设计方法的优越性和有效性。
This paper is concerned with the problem of analyzing and designing robust H∞ controllers for time- delay systems which have uncertainties in both state and control input with norm bounded time - varying uncertainty. A sufficient condition for the given systems with H∞ properties is presented in terms of a certain linear matrix inequality (LMI), and by ,solving the LMI, get the designing method of the robust H∞ controllers. Finally an example is presented to illustrate the effectiveness and superiority of the design method.
