In PMSM motor control we are considering that the flux component id=0 what if id is not equal to zero? ie, in practical application a small value appears for id. when there is a value for id how will the whole equation change? how will the shift occur? How can we COMPENSATE this? Is there any available compensation terms for that?And also we are considering that the angle between the rotor is 120 degrees. but in practical situation the angle varies due to fabrication error from 120 to some other degrees . how will that effects the id, iq ?
Thanks,
