modelAsynchron_ctrl
Asynchronous machine, cage-rotor, for field-oriented control, 3-phase abc
Extends from Partials.AsynchronBase (Asynchronous machine base, 3-phase abc).
Information
This model is intended for field-oriented control. The input/output current-signals 'i_meas'/'i_act' represent the pu stator current in the rotorflux-fixed reference system:
first component ('field'): pu current in rotorflux d-axis
second component ('torque'): pu current in rotorflux q-axis (q 90deg pos vs d)
The mapping from current demand to voltage demand is based on the steady-state equations of the machine.
Equivalent circuit is on diagram layer of parameter record ACdqo.Machines.Parameters.*
More information see Partials.AsynchronBase.
