摘　　要：针对传统永磁同步电机控制是利用速度传感器获取实时速度信息而导致系统复杂性与成本增加的问题,提出一种基于SMC与SVPWM的永磁同步电机无速度传感器控制技术。在对滑模控制与空间矢量脉冲宽度调制理论分析的基础上建立了电机无速度传感器控制模型,并在MATLAB/Simulink平台下搭建了仿真模型,对电机转速与负载变化下的速度与位置跟踪性能进行仿真,结果表明所提出的控制技术在两种工况下具有良好的性能。对降低系统成本与复杂性,使得永磁同步电机具有更广泛的用途提供了参考。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 motor 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 applicable.
