Abstract
A reduced-order position observer with stator-resistance adaptation is applied for motion-sensorless synchronous reluctance motor drives. A general analytical solution for the stabilizing observer gain and stability conditions for the stator-resistance adaptation are given. The local stability of the position and stator-resistance estimation is guaranteed at every operating point except the zero frequency, if inductances are known accurately. The observer design is experimentally tested using a 6.7-kW synchronous reluctance motor drive; stable operation at low speeds under various loading conditions is demonstrated.
