模糊PID控制的一个很不错的程序

clear all;


a = newfis('myfis'); 
a = addvar(a,'input','E',[0 7]);
a = addmf(a,'input',1,'small','trimf',[0 1 4.333]);
a = addmf(a,'input',1,'big','trimf',[1.6667 6 7]); 
a = addvar(a,'output','U',[0 7]);
a = addmf(a,'output',1,'small','trimf',[0 1 4.333]);
a = addmf(a,'output',1,'big','trimf',[1.6667 6 7]); 
rulelist = [1 1 1 1;
            2 2 1 1];
a = addrule(a,rulelist); 
u = evalfis(4,a)
