摘要
在已知离散线性开关系统全局渐近稳定前提下 ,将线性开关系统切换问题转化为相应 T- S模型模糊区域划分问题。通过在线实时调整 T- S模型隶属函数参数来确定模糊区域 ,以二阶离散线性开关系统为例 ,给出了实现系统全局渐近稳定的模糊切换策略。该方法可扩展到高阶线性开关系统。计算机仿真证实该方法简捷、有效。
Supposing that a switched discrete time linear system is globally asymptotically stable, a fuzzy switch method for the system is presented. The switch problem of the system is changed into the areadividingproblemofthe corresponding fuzzy T S model which is then solved by adjusting the parametersinthemembershipfunctionsofthefuzzyT Smodel.The 2 dimensional system is considered as an example. In fact the fuzzy switch method is also suitable for 3 dimensional systems etc. The simulation result shows that the presented method is simple and effective.
