我做的s函数（无刷双馈电机模型），检查了好久，没有错误，可是波形不对
大家帮忙看看，我用s函数写的无刷双馈电机的模型没有错误，但是输出的转速和角速度的波形不对
不知道为什么:@Q
郁闷了好久了
请高手务必帮忙！！在此表示非常的感谢
我把我得模型和参考的文献穿上来
那个.doc的文荡下载下来后把扩展名改为.pdf即可打开
function = BDFM(t,x,u,flag)
%SIMOM Example state-space M-file S-function with internal A,B,C,D matrices
% This S-function implements a system described by state-space equations:
%
% dx/dt = A*x + B*u
% y = C*x + D*u
%
% where x is the state vector, u is vector of inputs, and y is the vector
% of outputs. The matrices, A,B,C,D are embedded into the M-file.

% See sfuntmpl.m for a general S-function template.

我也做了几个电机模型了

:victory: 问题解决了吗:@D 你那个simulink的模型怎么打不开呢？？？？？？ 我也很想学习一下这方面的东西！不过我刚刚开始,hai meiyou s henme jingyan ! 下来看看，我们也做无刷双馈，不是我们是直接用模块搭建的，还行。没有你这么复杂 我也在做无刷双馈，下来帮你看看昂
