摘要
在对永磁同步电动机数学模型和直接转矩控制理论进行了深入研究的基础上,提出了一种新颖的基于模型参考自适应(MRAS)的转速辨识方法。在此基础上,提出了基于MRAS的无速度传感器永磁同步电动机直接转矩控制的方案,最后进行了系统仿真。结果表明,采用无速度传感器实现的永磁同步电动机系统具有良好的动静态性能,可与有速度传感器控制系统相媲美。
A novel control method of sensor less speed direct torque control for permanent magnet synchronous motor（PMSM） based on MRAS were put forward in this paper after analyzing the mathematical mod- el of PMSM and the theory of direct torque control. At the same time a sensor less speed direct torque control system for PMSM was obtained, the system simulation model with Mat lab environment was established, and simulation results were offered. The results show that the system had many advantages such as small speed overshoot and fast response.
