| 摘 要： | 针对状态不可测的切换模糊系统,提出一类切换模糊控制系统的输出反馈控制问题.根据切换技术和常用的平行分布补偿(PDC)控制器设计方法,给出了切换模糊观测器和切换模糊控制器设计,使用共同Lyapunov函数、单Lyapunov函数和多Lyapunov函数方法,研究了使闭环输出反馈控制系统渐近稳定的充分条件,同时设计可以实现系统全局渐近稳定的切换律.主要条件以矩阵不等式形式给出,具有较强的可解性.仿真结果表明设计方法的可行性与有效性.

| Abstract: | The output feedback control of a class of uncertain fuzzy switching systems is presented for a fuzzy switching system to which the states are unmeasurable.According to the switching technique and conventional design of PDC(parallel distributed compensation) controller,a fuzzy switching observer and controller are provided.The sufficient conditions to ensure the asymptotically stable output feedback control of closed-loop system are studied using the joint,single and multiple Lyapunov functions,with the switching law designed to implement the global asymptotic stability of fuzzy switching systems.The main condition is given in terms of LMI that is highly solvable.Simulation result shows the feasibility and effectiveness of the design method. |
