Research on Sensorless Control Technology for Permanent Magnet Synchronous Motor Based on SMC and SVPWM
A sensorless control technology for permanent magnet synchronous motor based on SMC and SVPWM is proposed to address the problem of increased system complexity and cost caused by the use of speed sensors to obtain real-time speed information in traditional control.Based on the theoretical analysis of sliding mode control and space vector pulse width modulation,a speed sensorless control model for mo-tor is established,and a simulation model is built on the MATLAB/Simulink platform to simulate the speed and position tracking performance under motor speed and load changes.The results show that the proposed control technology has good performance under two working conditions.It provides a reference for reducing system costs and complexity,making permanent magnet synchronous motors more widely ap-plicable.
