摘要:
定义一种具有时滞和参数不确定性的离散Takagi Sugeno(T -S)模糊模型 ,研究基于此模糊模型的离散不确定时滞系统的模糊鲁棒控制问题。利用Lya punov稳定性理论 ,提出一种基于LMI的模糊鲁棒状态反馈控制器的新的设计方法 ,给出模糊反馈控制器存在的充分条件 ,证明模糊闭环系统的鲁棒全局渐近稳定性。算例仿真表明该方法的有效性。
Abstract:
A discrete Takagi-Sugeno( T- S) fuzzy model w ith t ime-delay and paramet ric uncer-tainties is defined, and the problem of the robust fuzzy cont rol for a class of uncertain discrete time-delay systems based on the fuzzy model is discussed. In terms of Lyapunov stability theo-rem, a new fuzzy robust cont roller via LMI is designed and the suf ficient condit ions for the ex-istence of fuzzy state feedback controllers are given. The robust g lobal asymptot ic stability of fuzzy closed-loop system is proved. A simulat ion ex ample is g iven to prove the effect iveness of the proposed method.
