摘    要:针对许多非线性系统存在的结构不确定和难以用精确数学模型表达等问题,在研究基本Takagi-Sugeno(T-S)模糊模型的基础上,通过增加一个隶属函数自由变量,利用线性矩阵不等式(LMI)设计了一个使得闭环系统渐进稳定的状态反馈控制器,并给出稳定条件.所得到的条件充分利用了前件变量隶属函数的结构信息和后件局部子系统之间的相互关系,降低了常规T-S模糊系统的稳定性条件的保守性和求解难度.通过仿真实例验证了该方法的可行性和有效性.

关 键 词:T-S模糊模型  模糊控制器  隶属函数  线性矩阵不等式(LMI)  不确定隶属度

Abstract:Many nonlinear systems are so uncertain that they are difficult to be described accurately with mathematical models.Following an analysis of the basic Takagi-Sugeno (T-S) fuzzy model,by adding a free variable in the membership function,we were able to design a state feedback controller using linear matrix inequalities (LMI).The controller made the closed-loop system tend to an asymptotic stability.Stable conditions made full use of relationships between constructive information about prior states and the co...
