摘　　要：本研究基于异步电机改造为永磁同步电机的控制系统设计与实现,通过在异步电机转子上添加永磁体,提高了电机的效率和功率因数。采用矢量控制原理,建立了电机的数学模型,并设计了相应的硬件和软件系统。实验结果表明,这一控制系统能够快速、准确地跟踪速度指令,具有良好的速度调节性能和稳定性,为电动汽车驱动系统提供了可行的解决方案。This study is based on the design and realisation of the control system of an asynchronous motor converted into a permanent magnet synchronous motor,which improves the efficiency and power factor of the motor by adding permanent magnets to the rotor of the asynchronous motor.Using the vector control principle,the mathematical model of the motor is established and the corresponding hardware and software systems are designed.The experimental results show that this control system can track the speed command quickly and accurately,has good speed regulation performance and stability,and provides a feasible solution for the electric vehicle drive system.
