1、离散论域模糊控制表的离线计算一、题目已知单变量两维输入，一维输出模糊控制器，其两维输入为E，EC，一维输出为I，论域均为E，EC，I∈{-6，-5，-4，-3，-2，-1，0，1，2，3，4，5，6}，E的论域划分为{NB，NM，NS，NZ，PZ，PS，PM，PB}，共8个模糊子集，其各自的隶属度函数如表1所示。EC和I的论域划分为{NB，NM，NS，ZE，PS，PM，PB}，共7个模糊子集，它们的隶属度函数都如表2所示。已知控制规则表如表3所示，试求解输出控制表（如当e=-6，ec=-6时，求输出i

2、=？，最终输出的控制表格式如如表4所示）。其中输入采用单点模糊法，输出清晰量采用加权平均法进行解模糊，可以用MATLAB编程计算。各变量的隶属度函数以及控制规则表如下：表1输入变量E的隶属度函数表E-6-5-4-3-2-10123456NB1.00.80.60.40.200000000NM0.20.61.00.60.200000000NS000.30.71.00.70.3000000NZ00000.10.61.0000000PZ0000001.00.60.10000PS0000000.30.71.00
