Parametric variance consideration in speed control of single-phase flux reversal machine

Abstract

The new flux reversal machine (FRM) has a simple robust rotor with a permanent magnet installed stator. 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 in the speed control 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 and it is applied for popular AC induction/synchronous machines for their robust performance.
