直接模糊自适应
 

求助！紧急求助！:confused::confused::confused:
这里有一段关于直接模糊自适应的程序，看不懂，希望各位专家能帮忙看一下。
function [sys,x0,str,ts] = spacemodel(t,x,u,flag)
[COLOR="Red"]switch flag,
case 0,
[sys,x0,str,ts]=mdlInitializeSizes;
case 1,
sys=mdlDerivatives(t,x,u);
case 3,
sys=mdlOutputs(t,x,u);
case {2,4,9}
sys=[];
otherwise
error(['Unhandled flag = ',num2str(flag)]);
end

end
end

下面我把其他段落的程序也附上，以及simulink仿真图，麻烦各位了。

回复: 直接模糊自适应
 

这是空间模型的s函数 和模糊没有关系 红色是s函数的文件 做一些初始定义
