Field Oriented Control of a Multi-Phase Asynchronous Motor with Harmonic Injection

The paper presents a new complex dynamic modeling of multi-phase asynchronous motors and investigates the Field-Oriented control applied to this type of machines. The newdynamic model is obtained in the state space using a complex rectangular transformation. The obtained model is complex, reduced-order and takes into account also the odd harmonicinjection of the motor. The Field-Oriented control is considered and discussed in the multi-phase general case and then implemented in Matlab/Simulink considering a specific numeric case. The simulation results validate the obtained complex model and the implemented control design.
