Design of Steering Motor Control System for Vehicle Based on Magnetic Encoder

采用磁编码器作为电机位置传感器,装配上采用90°差分方式摆放,有效消除共模噪声,并对采样信号进行软件滤波处理。电机控制系统采用矢量控制,采用转速环和电流环闭环控制方式实时控制电机的转速和电流。在基于CKS32F103C8T6芯片的硬件平台上,实现了对转向电机的控制,实验表明,该系统具有良好的控制性能。

The magnetic coder is used as the motor position sensor,90°differential arrangement is adopted for assembly to effectively eliminate common mode noise and software filtering of the sampled signal.The motor control system adopts vector control,using the speed loop and current loop closed-loop control method to control the speed and current of the motor in real time.The control of the steering motor is realized on the hardware platform based on the CKS32F103C8T6 chip,and the experimental results show that the system has good control performance.
