Mw. Degner et Rd. Lorenz, USING MULTIPLE SALIENCIES FOR THE ESTIMATION OF FLUX, POSITION, AND VELOCITY IN AC MACHINES, IEEE transactions on industry applications, 34(5), 1998, pp. 1097-1104
This paper presents an improved method of estimating flux angle, rotor
position, and velocity by tracking the position of spatial saliencies
in an ac machine. Specifically, a machine model is presented which ac
curately models the behavior of ac machines with multiple spatial harm
onic saliencies. The effects of multiple spatial harmonic saliencies o
n the estimation of flux angle, position, and velocity is analyzed, an
d methods are presented utilizing multiple spatial harmonic saliencies
to provide wide bandwidth, high accuracy estimates of flux angle, rot
or position, and velocity.
