电动汽车永磁同步电机无速度传感器矢量驱动系统的研究

Permanent Magnet Synchronous Motor for Electric Vehicles Speed Sensorless Vector Drive of System Research

结合电动汽车的发展趋势,对电动汽车电机驱动系统进行分析,将pmsm设为研究的主要对象,进行两方面具体的研究:pmsm的数学模型和其系统的矢量控制研究,在此研究的同时加入无速度传感器这一相关技术,运用模型参考自适应法(mras),详细介绍其理论原理以及如何进行速度辨识,并最终达到速度估算,通过相应仿真得到一些结论。

Combined with the development trend of electric vehicles, electric vehicle motor drive system was analyzed, the main object of study Pmsm was taken to carry out two specific research： Vector Control Research and Pmsm mathematical model system. In this study, while adding that speedless sensor technologies, the use of model reference adaptive method （mras）was made, the theoretical principles and how to identify the speed were introduced in detail, and eventually speeds were estimated by the corresponding simulation to get some conclusions.
