Seneorless Vector Control of Bearingless Permanent Magnet Synchronous Motor Based on Sliding Mode Observer
摘要
Abstract
A novel control strategy based on sliding mode observer was present for the purpose of solving the problems of cost and reliability caused by the mechanical sensor of the bearingless permanent magnet synchronous motor ( BPMSM) vector control system. The sliding-mode surface and the sliding-mode equivalent control method was used in the control system. And, the sliding-mode surface was defined on the errors between the actual and estimated currents. The estimated back-EMF was observed to calculate the angle and speed of the rotor. Simulation system of speed sensorless was constructed in MATLAB/Simulink environment and simulations of speed/angle identification for the rotor were carried out. The simulation results had showed that sliding mode observer speed/angle identification precision was very well and was able to achieve stable sensorless suspension running.关键词
