离散时滞区间广义系统的输出反馈H_∞控制

Output Feedback H-infinity Control for Discrete-time Time-delay Interval Singular Systems

研究一类离散时滞区间广义系统的输出反馈H∞控制问题。通过运用系统参数不等式方法给出离散时滞区间广义系统的等价描述,得到了等价描述后系统可解的充分条件,该充分条件不仅使给定系统满足H∞性能指标,而且使得闭环系统正则、因果、稳定。

The problem of output feedback robust control for a class of discrete-time time - delay interval singular systems is discussed. Firstly, a kind of equivalent decription of the discrete -time time-delay interval singular systems is given through the use of the system parameters inequality approach. Then a sufficient condition for the solvability of the problem is obtained. The sufficient condition guaranteed that the closed-loop system is not only satis- fying a prescribed norm bounded constaint, but also is regular, causal and stable.
