摘要
主要对非线性离散广义系统的输出反馈H∞控制器的设计问题进行讨论,首先利用广义Lya-punov函数和线性矩阵不等式,对系统的零解E-渐近稳定性问题进行分析,在此条件基础上给出系统零解E-渐近稳定且具有H∞范数约束的充分条件,然后设计系统的输出反馈H∞控制器,使得闭环系统具有同样的性能。
The design of output feedback H∞ controllers is discussed for nonlinear discrete singular systems. First of all, by means of generalized Lyapunov function and linear matrix inequalities, zero solution E - asymptotically stable is studied for the system, a sufficient condition is given such that the system is zero solution E - asymptotically stable and a H∞ norm constraint. And the output feedback H∞ controller is designed to guarantee the performance of the resulting closed-loop system.
