摘　　要：介绍了电动车永磁直流有刷电动机控制系统软硬件的设计.该系统采用HT48R50A-1和PIC16F7162个单片机分别进行上、下位机的控制.上位机主要用于人机对话;下位机用于电机运动控制并且具有过流检测、过欠电压检测和堵转保护等功能.两机通过I/0串行方式通信.直流电机转速采用基于IGBT管的脉宽调制PWM技术进行调节,控制算法采用软件模拟防积分饱和的PI调节器进行闭环控制.最后对系统抗干扰设计进行了介绍.This article introduces the design of software and hardware for permanent magnet DC motor with brush control system in an electric vehicle. The system uses two microprocessors, HT48RSOA- 1 and PIC16FT16, to control the upper and lower machines separately. The upper machine mainly uses human-machine interaction ; with the function of over-current detection, less voltage detection and stall protection, the lower machine is used for the control of motor motion. The two microprocessors communicate by I/O. The system implements the IGBT-based pulse width modulated （PWM） control technique to regulate the velocity of DC motor. The algorithm is a closed loop based on software simulation with anti-saturation point PI controller using velocity feedback. Finally, the design of control system anti-interference is introduced.
