Research on Switching Control of Brushless Permanent Magnet Motor for EMA for Aerospace

Abstract:

The switching system is one of the important models which describe the hybrid dynamical systems. Different models and the switching rules are adopted to better describe the motion of the actual complicated systems. Combined with advantages of the PMSM and BLDCM, the paper proposed the switching control strategy for Brushless PM Motor with the rule of output feedback based on switching system theory. Then the linear model of the switching control system was obtained and the stability of it was analyzed. The results of the simulation and the experiment show that the switching control strategy is stable and could effectively improve the efficiency and reduce the torque ripple of the motor in full speed range.
