Abstract:


Background: This document presents a new approach to estimate speed and rotor position of the salient-pole PMSM. Methods: To eliminate the mechanical sensors, we apply a sensorless field oriented control (FOC) by using an improved full-order sliding mode observer (FO-SMO) at different speeds (low and high speeds). The stability of the SMO was demonstrated with the Lyapunov function. Result: The simulation results prove good properties of the proposed estimation method.
