四川理工学院毕业设计数字式直流电机控速系统设计学 生:张 平学 号:09021020247专 业:电子信息工程班 级:2024.2指导老师:王贤秋 四川理工学院自动化与电子信息学院二 O 一三年六月数字式直流电机控速系统设计摘要:本设计采纳脉宽调制的方法实现电机的控速,利用单片机在控制方面简单灵活操作特点,通过检测光栅的方式实现了电机的转速测量,再通过相应的处理生成控制信息之后,采纳调节占空比的方式控制电机的转速。并且为了适应联机操作,本设计电路还提供了一个串行接口提供给上位机发送命令以及接收数据使用。 关键词:数字式;直流电机;光栅控速;串行通信DC motor digital speed control systemZhangPing(Sichuan University of Science and Engineering, Zigong, China, 643000) Abstract: This article make the control of the motor by pulse duration modulation. This article use a kind of simple and practical design solution .By help of Single Chip Micyoco , we could do something more flexible . the system can compute the speed of the motor by checking the optical grating . when get the data , it will dispose the data with a corresponding way , and then control DC motor by adjusting the PWM . on the other side , online is very important for a system , so to communicate with other system , the system support a Serial interface ,too .
