Park's transformation
显示 更早的评论
How to implement a dq to abc Park's transformation by writing a code in mfile (and not using Simulink). Anyone who cud share such file? I tried using symbolic math but am unable to find abc-frame answers in polar form.
Thanks for ur time.

clear,clc,clf;
Vm=30000*sqrt(2);
w=2*pi*50;
T=1/50;
dt=1e-4;
k=0;
for t=0:dt:50*T
k=k+1;
tt(k)=t;
Va(k)=Vm*sin(w*t);
Vb(k)=Vm*sin(w*t-(2*pi/3));
Vc(k)=Vm*sin(w*t+(2*pi/3));
end;
%grid on;
%plot(Va);
%hold on;
%plot(Vb);
%hold on;
%plot(Vc);
k=0;
for t=(2*pi/(3*w)):dt:50*T
k=k+1;
Vd(k)=(2/3)*(Va(k)*sin(w*t)+Vb(k)*sin(w*t-2*pi/3)+Vc(k)*sin(w*t+(2*pi/3)));
Vq(k)=(2/3)*(Va(k)*cos(w*t)+Vb(k)*cos(w*t-2*pi/3)+Vc(k)*cos(w*t+2*pi/3));
Vo(k)=(1/3)*(Va(k)+Vb(k)+Vc(k));
end
subplot(3,1,1);
grid on;
plot(Vd);
subplot(3,1,2);
hold on;
plot(Vq);
subplot(3,1,3);
hold on;
plot(Vo);

But in the result we do not get any vector diagram in dq-plane. Do you know how we can generate vector diagram which traces the d q variables after anytime t.
