Attaching a simulink model, can anyone tell the equations governing ?

Answer 1

[Sulaymon Eshkabilov]

It is quite simple as follows:

2/3*(va*cos(theta)+vb*cos(theta-2*pi/3)+vc*cos(theta+2*pi/3))=vd

-2/3*(va*sin(theta)+vb*sin(theta-2*pi/3)+vc*sin(theta+2*pi/3))=vq

Thanks Sulaymon Eshkabilov,

I got the equation. Thanks for your insight.

Hello Sulaymon,

I had another doubt too. It would be helpful if you can provide me with some insights.

I had modeled a PMSM system with all subsystem, The results showed is not correct.

I am attaching the simulink and .m file for your reference.
