摘要
利用 T- S模型对一类非线性不确定系统进行模糊建模 ,在此基础上研究模糊鲁棒观测器及模糊状态鲁棒控制器的设计 ,并证明所设计的模糊鲁棒观测器和模糊状态鲁棒控制器具有全局渐近稳定性质。
The output stabilization problem of uncertain nonlinear systems was considered. The uncertain nonlinear systems were modeled by Takagi-Sugeno fuzzy models. A robust form of observers for such models was given. Fuzzy robust state feedback controllers based on fuzzy observers were designed. It was shown that state feedback robust controller and robust observer would yield stabilizing output feedback control providing the stabilizing property of control and the asymptotic convergence of observer.
