1、內蒙古科技大學本科生畢業(yè)設計說明書（畢業(yè)論文）題 目：基于 AT89C51 單片機的步進電機控制系統學生姓名： 學 號：專 業(yè)：自動化班 級：自動化 06-3 班指導教師： 內蒙古科技大學畢業(yè)設計說明書（畢業(yè)論文）IIBased on AT89C51 Single-chip ComputerStepping Motor Control SystemAbstractStepping motor is a kind

2、of digital control system components. It can achieve quick start-up, positive inversion, stopping and speed control, according to the control pulse. It has high precision step angle, and can be self-locking when it keeps

3、 still. As these characteristics, stepping motor in automatic control system, especially in the open loop control system has been widely applied.This article mainly focuses on taking Single-chip Computer and cycle pulse

4、distributor as the core, and designing the stepping motor control system. Through the design of the software and hardware debugging, it realizes controlling the step motor’s acceleration and deceleration automatically, a

5、ccording to parameter setting. Making the system arrive the end point with the shortest time, but not occur outing of step. Besides it can accurately achieve start-up, positive inversion and shutdown. Hardware takes AT89

6、C51 as the core of control circuit, mainly including: cycle pulse distributor, keyboard and display circuit, stepping motor driving circuit, etc. Software part adopts the C language programming, mainly including keyboard
