摘　　要：电动机驱动技术是电动车的核心技术之一。随着永磁体技术和电力电子技术的不断发展,永磁同步电机(PMSM)在新能源电动车领域得到了越来越广泛的应用。在电动车驱动系统中,电动机启动响应的快速性和稳定性对电动车的动态性能和驾驶性能具有重要影响。为了实现永磁同步电动机良好的启动效果,结合永磁同步电动机的数学模型,对基于磁场定向控制技术(FOC)下的永磁同步电动机启动过程及其控制系统中影响电动机启动效果的转子位置检测、定子电流检测以及PI控制器参数调节等关键技术进行了系统地研究与分析。在此基础上,完成了永磁同步电动机磁场定向控制系统的设计。并在实验室环境下,利用测功机模拟电动车在不同路面状况下的负载工况,使电动机取得了快速、平稳的启动效果。The performance of motor drive system is one of those factors that determine the driving quality of electric vehicle.As the development of Permanent magnet technology and power electronics,permanent magnet synchronous motor has got more and more applications in the new energy automobile industry and,the rapidity and stability is very important to EV's dynamic property and drivability in motor starting process.To achieve the favourable starting effect of PMSM,the research and analysis on PMSM starting process and the critical factors like i.e.rotor position detection,stator current detection and the PI controller design were completed in this paper.At the same timeMeanwhile,the FOC control system of PMSM was designed.Finally,with the help of dynamometer in the lab,some simulation were made based on the different road conditions were simulated.Through those experiments,the speedability and the stability in the motor starting process have been achieved.
