Abstract

An outer rotor coreless bearingless permanent magnet synchronous generator (ORC-BPMSG) has the characteristics of long service life, high efficiency, low noise, etc. However, the stability and reliability of the system and the output voltage are affected by the rotor vibration. In this paper, the step size and error of improved variable step least mean square (VSLMS) adaptive filter using improved simplified particle swarm optimization (ISPSO) is proposed, which suppresses the vibration of the rotor. The mathematical model and working principle of the ORC-BPMSG are introduced. The performances of improved VSLMS adaptive filter parameters are optimized by the improved SPSO algorithm, which generates a compensation signal to realize vibration compensation. The simulation system for the vibration compensation of the ORC-BPMSG is constructed, and dynamic suspension experiment and variable speed experiment of the rotor are carried out, which verify the robustness and stability of the proposed method.
