Research on a solution to eliminating position noise in a Slotless Self-Bearing Motor control system

Abstract

The content of this paper presents a solution to avoid noise for the SSBM motor control system. First, this paper analyzes the theoretical basis of situations where noise can affect motor operation. Then, the authors developed a method of direct current supply to maintain lift and the current transformation from the axis (X, Y) to the axis (ad, be, and cf) to eliminate the phenomenon of reverse braking torque. In addition, the authors also added a noise-compensating feed-forward control in the position control system. To demonstrate this solution, the SSBM motor control system was built on Matlab/Simulink. Simulation results have shown the ability to eliminate position noise, which helps the Slotless Self-Bearing Motor system to operate more stably.
