Position tracking control of a synchronous reluctance motor

The synchronous reluctance (SynR) motor is an attractive candidate for high-performance servo drive systems for various reasons. An integrator back-stepping technique is used to design a trajectory tracking control strategy for SynR motors driving inertial loads. A d-q model which describes the dynamic behavior of the SynR motor is introduced; based on this model, a voltage level controller is proposed which theoretically provides globally uniform asymptotically stable (GUAS) motor trajectory tracking given exact model knowledge and full state feedback (i.e., rotor position, velocity, and the per phase winding currents). The performance of the proposed voltage level controller is verified using computer simulation
