PARAMETRIC VARIANCE CONSIDERATION IN SPEED CONTROL OF FLUX REVERSAL MACHINE

Abstract

The flux reversal machine (FRM) is a new machine that has a simple robust rotor with a permanent magnet installed stator. [Y. Liao et al., 1995][T.A. Lipo et al., 1997] However, the parameters of the FRM are dependant on the position of the rotor, operating temperature and magnetic saturation of the motor core. To obtain a robust performance of the single phase FRM, a control method that introduces an internal model of the motor is suggested for robustness against parameter variance and disturbance. The suggested control method is verified by both computer simulation and experiments
