摘　　要：针对一类切换模糊组合系统,在控制器增益存在摄动情况下,利用单Lyapunov函数方法和多Lyapunov函数方法,给出非脆弱控制器存在条件,并给出分散切换律设计方法,使得系统在原点渐近稳定,相应结果以矩阵不等式形式给出。最后通过数值仿真例子验证方法的有效性。For a class of the switched fuzzy composite systems,the existing condition of the non-fragile controller was suggested and hereby the design method of decentralization switched laws was also given via single Lyapunov function and multiple Lyapunov function method in the case of controllers gain perturbation,to the effect that the closed-loop system was asymptotically stable.The corresponding results were given in the form of matrix inequalities.The simulation result expatiate that the design method is effective after numerical simulation.
