Simulation Analysis of Position Sensorless Direct Torque Control for Permanent Magnet Synchronous Motor

本文建立了永磁同步电动机定子坐标系下的数学模型和无位置传感器永磁同步电动机直接转矩控制系统的MATLABSIMULINK仿真模型,并详细推导一种基于积分器的无传感器位置与速度算法。通过仿真结果验证了基于积分器的算法具有简洁、响应迅速的特点。

This paper analyses the mathematic model of permanent magnet synchronous motor and the theory of direct torque control and proposes an estimation method of position sensorless direct torque control for permanent magnet synchronous motor, which is based on integrator. Simulation is carried out by Matlab proving that the estimation method based on integrator is brief and quick in response, the results are shown in the end.
