摘要
介绍了应用线性矩阵不等式(LMI)解决一类时滞系统H∞控制问题,给出了基于Lyapunov第二法的H∞稳定条件,通过求解锥补线性化问题,得到相应的控制器,使得闭环系统稳定且满足H∞性能指标。并通过实例给出了仿真结果。
In this paper, how to solve Hoo control problem in a kind of time-delay system by using linear matrix ine- quality(LMI) is studied. Based on Lyapunov second method, we present the H∞ stability condition. Through solving the corresponding Cone Complementary Liberalization problem, the controller is designed to make the closed-loop system asymp- totically stable and satisfy the H∞ performance. And an example is presented to show the simulation result.
