摘要
针对一类具有能量有界外部干扰的连续时变线性随机系统,研究了在H2 增益约束下闭环系统的有限时间有界性.首先,给出系统有限时间有界和H2 增益的定义.然后,设计状态反馈控制器,使得闭环系统既满足H2 增益性能约束又满足有限时间有界.通过求解时变线性矩阵不等式,得到控制器增益函数.最后,给出两个数值算例说明所设计方法的有效性.
Abstract
In light of a class of continuous time-varying linear stochastic systems with energy-bounded external interference,this paper studied the finite-time boundedness(FTB)for closed-loop systems with H2 gain constraint.Firstly,the definitions of FTB and H2 gain were introduced.Then,a state feedback controller was designed to ensure the finite-time boundedness as well as the H2 gain constraint performance of the closed-loop system.By solving time-varying linear matrix inequalities,the controller gain function was obtained.Finally,two numerical examples were given to illustrate the effectiveness of the devised method.
