随着人们生活水平的不断提高,利用汽车作为代步工具的需求逐渐加大,传统燃油汽车带来的环境污染问题也越来越引人关注,因而节能环保的新能源汽车受到了很大的重视,纯电动汽车和混合动力汽车得到广泛的应用和普及,电机控制器成为新能源汽车的一个新研究领域。文章针对纯电动汽车电机控制器的传感器及其处理电路,电机转速控制策略进行了进入研究。首先介绍直流电机控制器的组成,然后描述了直流电机控制器的传感器及其处理电路,并根据传感信号研究直流电机的转速控制策略。最后通过matlab simulink软件对电机的转速控制策略进行仿真试验,试验结果良好。

With the continuous improvement of people's living standards, the demand for using automobiles as a means of transportation is gradually increasing, and the environmental pollution caused by traditional fuel vehicles is attracting more and more attention. Therefore, new energy vehicles with energy saving and environmental protection have been paid great attention to. Pure electric vehicle (EV) and hybrid electric vehicle (HEV) have been widely used and popularized. Motor controller has become a new research field of new energy vehicle. In this paper, the sensor of motor controller of pure electric vehicle and its processing circuit, motor speed control strategy are studied. Firstly, the composition of DC motor controller is introduced, then the sensor and its processing circuit of DC motor controller are described, and the speed control strategy of DC motor is studied according to the sensing signal. Finally, the control strategy of motor speed is simulated by matlab simulink software, and the result is good.
