| 摘 要： | 直接转矩控制是一种高性能的交流传动控制系统,无速度传感器控制的研究代表了直接转矩控制系统的一个发展方向.在空间矢量模型基础上,介绍一种新的无速度传感器永磁同步电动机的直接转矩控制,它能降低稳态时转矩、磁链和速度的波动.在全速范围无速度传感器应用中,能产生更好的稳态性能的同时保留了DTC的暂态优点.仿真结果显示,该方法有着比传统的DTC更好的性能.

| Abstract: | Direct torque control is a new-style control technique for AC driving.Speed sensorless control is one of the most important directions of development for DTC. A new direct torque control was introduced,that is based on space vector modulation for permanent magnet synchronous motor speed sensorless drive.It can reduce the torque,flux and speed pulsation during steady state.Simulation results show that the proposed control produces better results for steady-state operation than the classical DTC for a wide speed range,and the DTC transient merits are preserved. |
