Model Predictive Torque and Flux Control Minimizing Current Distortions

Model Predictive Torque and Flux Control Minimizing Current Distortions

A new model predictive torque and flux controller is proposed, which controls the electromagnetic torque and rotor (rather than the stator) flux magnitude. Analytical expressions for the weighting factors are derived that ensure that the proposed controller achieves the same closed-loop performance...

Zusammenfassung:A new model predictive torque and flux controller is proposed, which controls the electromagnetic torque and rotor (rather than the stator) flux magnitude. Analytical expressions for the weighting factors are derived that ensure that the proposed controller achieves the same closed-loop performance as predictive current control. In particular, the same low current and torque distortions result, without requiring an outer field-oriented control loop.
