Simulation Study on Vector Control of Permanent Magnet Synchronous Motor of Pure Electric Vehicle

随着汽车领域电动汽车的发展正如火如荼的进行,对其动力驱动系统(即电机驱动)需要达到更高的要求和精确的控制。对于车用电机,需要做到小体积,大功率,快响应,高效率等诸多要求,以此来实现纯电动汽车的各工况稳定运行。与其他类型的电机相比,永磁同步电机因其结构简单,调速范围宽,可控性好等优点成为电动汽车用主流的电机[1]。通过建立PMSM的数学模型和空间矢量算法,得到一种转速,电流双闭环控制方法。以此方法建立PMSM空间矢量控制Simulink模型,并且进行仿真分析。

With the development of electric vehicles in the automotive field is in full swing,its power drive system (that is,motor drive) needs to achieve higher requirements and accurate control.For automotive motors,it is necessary to achieve many requirements,such as small size,high power,fast response,high efficiency,etc.,so as to achieve the stable operation of pure electric vehicles in various working conditions.Compared with other types of motors,PMSM has become the mainstream motor for electric vehicles due to its simple structure,wide speed regulation range,good controllability and other advantages[1].Through the establishment of PMSM mathematical model and space vector algorithm,a speed,current double closed loop control method is obtained.In this way,PMSM space vector control Simulink model is established and simulated.
