## Matlab 利用M文件产生模糊控制器 ##

有位朋友咨询了一个问题，想要通过粒子群优化模糊控制的论域范围，在这种情况下，就无法直接通过matlab的fuzzy工具箱来自动生成fis模糊文件，需要通过M文件生成模糊控制器，并写成函数方便调用，

前期模糊控制和粒子群传送门：

给出一个样例如下：

%%clcclose allclearFIS = newfis('FIS','sugeno');%%% 定义输入E:FIS = addvar(FIS,'input','E',[-10 10]);
    FIS = addmf(FIS,'input',1,'Negative','gaussmf',[7 -10]);
    FIS = addmf(FIS,'input',1,'Positive','gaussmf',[7 10]);
    %%% 定义输入CE:
    FIS = addvar(FIS,'input','CE',[-10 10]);
    FIS = addmf(FIS,'input',2,'Negative','gaussmf',[7 -10]);
    FIS = addmf(FIS,'input',2,'Positive','gaussmf',[7 10]);
    %%% 定义输出u:
    FIS = addvar(FIS,'output','u',[-20 20]);
    FIS = addmf(FIS,'output',1,'Min','constant',-20);
    FIS = addmf(FIS,'output',1,'Zero','constant',0);
    FIS = addmf(FIS,'output',1,'Max','constant',20);
    %%% 定义规则:% 格式：输入1~ 输入2~ 输出~ 权重（默认为：1)逻辑关系（1=and;2=or)ruleList = [1 1 1 1 1;...   % Rule 1
           1 2 2 1 1;...   % Rule 2
           2 1 2 1 1;...   % Rule 3
           2 2 3 1 1];         FIS = addrule(FIS,ruleList);
