Output Feedback Fuzzy Control of Nonlinear Fuzzy Impulsive Systems

研究了非线性模糊脉冲系统的静态输出反馈鲁棒模糊控制问题.基于线性矩阵不等式(LMI)方法提出了一种静态输出反馈模糊控制新方案.采用并行分布补偿(PDC)的基本思想设计输出反馈控制器,并利用Lyapunov方法理论证明闭环系统以全局指数稳定.最后基于LMI方法,将鲁棒模糊控制器的设计问题转化为线性矩阵不等式问题(LMIP).仿真表明了本方法的有效性.

The problem of robust output feedback fuzzy control of nonlinear fuzzy impulsive systems is considered in this paper. A new scheme of robust fuzzy control via linear matrix inequality （LMI） technique is proposed. The concept of parallel distributed compensation （PDC） is employed to design the static output feedback controller. By Lyapunov method, the resulting closed-loop system is shown to be globally exponential stable. By LMI technique, the problem of designing the robust fuzzy controller is translated into linear matrix inequality problem （LMIP）. The simulation shows the effectiveness of the proposed controller design methodology.
