while executing a m-file it shows busy?
显示 更早的评论
I am working on PV Cell modelling. I came across a matlab code and while running the m file it shows busy.
clc;
clear all;
T=25+273;
Tn=25+273;
dT=T-Tn;
G=800;
Gn=1000;
Imp=7.61;
Vmp=26.3;
Iscn=8.21;
Vocn=32.9;
Pmaxe=Vmp*Imp;
Kv=-0.1230;
Ki=0.0032;
Ns=54;
k=1.38065e-23;
q=1.602e-19;
a=1.3;
Vtn=k*Tn/q;
Vt=k*T/q;
Rpmin=(Vmp/(Iscn-Imp))-((Vocn-Vmp)/Imp);
Rp=Rpmin;
Rs=0;
Io=(Iscn+(Ki*dT))/((exp((Vocn+(Kv*dT))/a*Vt))-1);
P=(0);
err=inf;
tol=0.01;
while(err>tol)
Ipvn=(((Rs+Rp)/Rp))*Iscn;
Ipv=(Ipvn+(Ki*dT))*(G/Gn);
Isc=(Iscn+(Ki*dT))*(G/Gn);
Rs=Rs+0.01;
b=exp(((Vmp+(Imp*Rs))*q)/(Ns*a*k*T));
Rp=(Vmp+(Imp*Rs))/((Vmp*Ipv)-(Vmp*Io*b)+(Vmp*Io)-Pmaxe);
clear V
clear I
V=0:0.1:50;
I=zeros(1,size(V,2));
g=zeros(1,size(V,2));
glin=zeros(1,size(V,2));
I_=zeros(1,size(V,2));
for j=1:size(V,2)
g(j)=Ipv-(Io*exp(V(j)+(Rs*I(j)))/(Vt*a*Ns))+Io-((V(j)+(Rs*I(j)))/Rp)-I(j);
while(abs(g(j))>0.001)
g(j)=Ipv-(Io*exp(V(j)+(Rs*I(j)))/(Vt*a*Ns))+Io-((V(j)+(Rs*I(j)))/Rp)-I(j);
glin(j)=-(Io*exp((V(j)+(Rs*I(j)))/(Vt*a*Ns))*Rs/(Vt*a*Ns))-(Rs/Rp)-1;
I_(j)=I(j)-(g(j)/glin(j));
I(j)=I_(j);
end
end
P=(Ipv-(Io*exp((V+(I.*Rs))/(Vt*a*Ns)))+Io-((V+(I.*Rs))/Rp)).*V;
Pmax=max(P);
err=(Pmax-Pmaxe);
end
fprintf('Model info:-\n');
fprintf('Rp=%f',Rp);
fprintf('Rs=%f',Rs);
fprintf('Pmax=%f',Pmax);

What is your question? Matlab always shows busy when it is busy. It's a feature.

It is getting in stuck while performing while loop inside for loop ( while(abs(g(j))>0.001)). Check your code for mistakes, because there are situations when (abs(g(j))>0.001) cannot be false.

Add a counter that you increment each time through your while loop. Include in your while condition both a check on the value of g(j) and a check that the counter is not too large. After the while loop, if the counter is too large you didn't converse and you can handle that case appropriately.

How did you solve this problem, i couldn't get it?
