Flux-Vector Control

These examples demonstrate flux-vector control of electric machine drives [1]. In the implemented control system, decoupling between the stator flux and torque channels are used according to [2]. Furthermore, the stator flux magnitude and the electromagnetic torque are selected as controllable variables. The implementations correspond to [3] for synchronous machines and [4] for induction machines. The magnetic saturation is modeled and taken into account in control.
