Abstract
A novel 6/13-pole hybrid excitation axial field flux-switching permanent magnet machine (HEAFFSPMM) has the advantages of strong fault tolerance ability, high efficiency and large torque density. In order to carry out the operation of HEAFFSPMM without position sensor, an improved control method is proposed and studied in this paper, which is based on model reference adaptive system (MRAS) to detect position and speed. The related experiments are done to validate the control method. The results show that the proposed position sensorless control method has better performance and higher control precision under light and heavy load in contrast with the traditional MRAS method.
