Description
TheInduction Machine Field-Oriented Controllerblock implements an induction machine field-oriented control (FOC) structure using the per-unit system. To decouple the torque and flux, FOC uses the rotord-qreference frame. The figure shows the control structure.
In the diagram:
ωris the measured angular velocity.
ωrefis the reference angular velocity.
idandiqare thed- andq-axis stator currents.
ia,ib, andicare thea-,b- andc-phase stator winding currents.
imr_refis the reference magnetizing current.
imris the magnetizing current.
vdandvqare thed- andq-axis stator voltages.
va,vb, andvcare thea-,b- andc-phase stator winding voltages.
θeis the rotor electrical angle.
GAH,GAL,GBH,GBL,GCH, andGCLare thea-,b- andc-phase high (H) and low(L) gate pulses.
Assumptions and Limitations
The machine parameters are known.
The implementation uses the per-unit system.
The control structure implementation uses a single sample rate.
