| 摘 要： | 研究了连续时滞T-S模糊模型基于Lyapunov-Krasovskii函数的稳定性分析及控制器设计问题.构造出连续型Lyapunov-Krasovskii函数,然后基于一系列线性矩阵不等式,得到了开环系统稳定的充分条件,该条件具有较少的保守性.进而给出状态反馈控制器设计方法,所设计的控制器能保证闭环系统渐进稳定.最后通过仿真实例验证了该方法的有效性和优越性.

| Abstract: | The new generalized delay-dependent stability conditions of Takagi-Sugeno fuzzy time-delay systems are studied.A generalized Lyapunov-Krasovskii function is chosen and a parameterized model transformation with free weighting matrices is introduced to it,in order to obtain generalized delay-dependent stability conditions.Our delay-dependent stability conditions thus obtained are given in terms of linear matrix inequalities(LMIs).Finally,simulation example shows the validity and advantage of the proposed meth... |
