谁能帮我看看异步机的数模 S-函数啊
:@Q 为什么老是又错误啊？哪位大侠行侠仗义啊
帮帮忙呀
急用呀！
多谢多谢啊！
输入是Us,Is,n0,输出是磁链Ψα，Ψβ与转矩Tf
%异步机模型的S-函数
function = ybj(t,x,u,flag)
switch flag,
%Initialization
case 0,

%Derivatives
case 1,
sys=mdlDerivatives(t,x,u);
%Output
case 3,
sys=mdlOutputs(t,x,u);
%Terminate
case {2,4,9}
sys=[];
otherwise
error(['Unhandled flag = ',num2str(flag)]);
end

谢谢啊谢谢！ 本版面有关于电机的S函数的帖子，自己搜索 出错在什么地方,因为你只给了s函数,单从程序上看没有错啊
