线性离散系统的鲁棒控制器综合

Robust Controller Synthesis for Linear Discrete Time System

利用Ｋｈａｒｉｔｏｎｏｖ定理及其在离散时间域中的推广结果，针对线性离散区间对象讨论了鲁棒状态反馈控制器的设计，完成了稳态二次型鲁棒控制器综合，使得对于对象集合中的所有线性离散系统均为稳定的，且系统性能满足所给定的二次型指标．

The design of robust state feedback controller for linear discrete time interval plants is studied by using Kharitonovs theorem and its discrete time counterparts.Based on this result,the robust controller synthesis is also fulfilled under steady LQ index,which guarantees the stability of all linear discrete time systems in plant set and makes system performance satisfy the given LQ index.A corresponding example is provided.
