Implementation of Linear Extended State Observer for Sensorless Control of PMSM based on HF Pulsation Signal Injection

Abstract

In this essay, a LESO and HF pulsation signal injection are combined for get rotor position. The stability and astringency of the LESO are studied. Chebyshev II filter is used to reduce the noise of the HF response signal. The simulated outcomes show the validity and accuracy of the proposed estimation design.
