纯电动汽车永磁同步电机控制技术研究

Research on Control Technology of Permanent Magnet Synchronous Motor for Pure Electric Vehicle

纯电动汽车和传统汽车的差异性主要是动力源不同,传统汽车一般是依靠发动机,利用石化能源提供动力,而纯电动汽车是借助电动力依靠蓄电池提供动力。纯电动汽车不存在尾气排放,行驶过程中噪声较小,和传统汽车比起来更加环保节能。与此同时,纯电动汽车保养成本相对传统汽车更低,家庭用车经济性较好,因此近年来也受到了越来越多消费者的青睐。国内目前研发生产的大部分纯电动汽车都选择永磁同步电机进行控制,本文结合笔者实际研究,针对纯电动汽车永磁同步电机控制技术进行探讨。

The main difference between pure electric vehicle and traditional car is the power source.Traditional car generally relies on engine to power with petrochemical energy,while pure electric vehicle relies on battery to power with electric power.Pure electric vehicle does not have exhaust emission,has less noise during driving,and is more environmentally friendly and energy-efficient than traditional car.Meanwhile,pure electric vehicle is more energy-efficient than traditional car.The maintenance cost of electric vehicle is lower than that of traditional car,and the economy of domestic car is better,so it has been favored by more and more consumers in recent years.Most pure electric vehicles developed and produced in China now choose permanent magnet synchronous motor control.This paper combines with the author's actual research,and discusses the control technology of permanent magnet synchronous motor for pure electric vehicle.
