This work presents a self-sensing control for permanent-magnet synchronous motor (PMSM) for wide-speed range based on the integration of signal-injection and back-emf tracking methods. It is addressed an evaluation method of the transition region between these approaches based on the harmonic content of the q-axis reference current during self-sensing operation. Based on the procedure, it is established the bandwidth of the rotor position observers in function of the operation speed. It is also addressed the discussion of the attributes of implementation required for integration between the self-sensing techniques. Simulation results are presented showing the performance of the proposed self-sensing wide-speed range system.
