Abstract

This paper presents an improved method of estimating the flux angle, rotor position and velocity by tracking the position of spatial saliencies in an AC machine. Specifically, a machine model is presented which accurately models the behavior of AC machines with multiple spatial harmonic saliencies. The effects of multiple spatial harmonic saliencies on the estimation of flux angle, position and velocity is analyzed, and methods are presented utilizing multiple spatial harmonic saliencies to provide wide bandwidth, high accuracy estimates of machine flux angle, rotor position and velocity
