针对T-S模糊控制系统,为了更好地利用模糊划分的结构信息来降低稳定分析的保守性,在模糊规则输入空间的一种划分方式下,研究了T-S模糊模型的一些性质.然后用扩展的Lyapunov分析方法,获得了保守性更低的稳定性充分条件.最后,通过仿真实验验证了结论的有效性.
For T-S fuzzy control systems, in order to make good use of structural information in the fuzzy partition to decrease conservatism of stability analysis, some properties of the complete standard T-S fuzzy control systems are studied. Using extended Lyapunov theory, a relaxed stability condition is obtained. Simulation results show effectiveness of the proposed method.
