s-function parameters怎样设置？
基于S函数的BLDCM（无刷直流电机）本体模块设计中，求其反电势的S函数主要程序如下：function=mdlOutputs(t,x,u,k)
sq3=1.732050808;
pos=u(1);
w=u(2);
sq=0.866025;
per=fix(pos/2/pi)*360;
if(sin(pos)<sq3/2)&(cos(pos)>0.5)&(sin(pos)>=0),
fa=1;fb=-1;fc=((per-pos*180/pi)/30+1);end;
if(sin(pos)>sq3/2)&(abs(cos(pos))<0.5),
fa=1;fb=((pos*180/pi-60-per)/30-1);fc=-1;end;
if(sin(pos)<sq3/2)&(cos(pos)<-0.5)&(sin(pos)>=0),
fa=((per+120-pos*180/pi)/30+1);fb=1;fc=-1;end;
if(sin(pos)>-sq3/2)&(cos(pos)<-0.5)&(sin(pos)<0),
fa=-1;fb=1;fc=((pos*180/pi-180-per)/30-1);end;
if(sin(pos)<-sq3/2)&(abs(cos(pos))<=0.5),
fa=-1,fb=((per+240-pos*180/pi)/30+1);fc=1;end;
if(sin(pos)>-sq3/2)&(cos(pos)>0.5)&(sin(pos)<0),
fa=((pos*180/pi-300-per)/30-1);fb=-1;fc=1;end;
ean=k*w*fa;
ebn=k*w*fb;
ecn=k*w*fc;
sys=;
elseif flag==0,
x0=[];
sys=;
请问它的s-function parameters该怎么设置啊？
还有其参考电流模块的S函数主要程序如下：
function sys=mdloutputs(t,x,u,k)
sq3=1.732050808;
pos=u(1);
sq=0.866025;
per=fix(pos/2/pi)*360;
if(sin(pos)<sq3/2)&(cos(pos)>0.5)&(sin(pos)>=0),
iar=ir;ibr=-ir;icr=0;end;
if(sin(pos)>sq3/2)&(abs(cos(pos))<0.5),
iar=ir;ibr=0;icr=-ir;end;
if(sin(pos)<sq3/2)&(cos(pos)<-0.5)&(sin(pos)>=0),
iar=0;ibr=ir;icr=-ir;end;
if(sin(pos)>-sq3/2)&(cos(pos)<-0.5)&(sin(pos)<0),
iar=-ir;ibr=ir;icr=0;end;
if(sin(pos)<-sq3/2)&(abs(cos(pos))<=0.5),
iar=-ir;ibr=0;icr=ir;end;
if(sin(pos)>-sq3/2)&(cos(pos)>0.5)&(sin(pos)<0),
iar=0;ibr=-ir;icr=ir;end;
sys=;
同样请问其s-function parameters该怎么设置啊？
多谢各位！！！跪求等待中。。。
