多功能电机驱动系统的设计研究 摘 要 电机本体及其控制技术在近几年取得相当大的进步。这要归功于半导体技术的空前发展带来的电力电子学领域的显著进步。电机驱动产业发展的利处已经触及各种各样的设备，从大型工业设备像钢铁制造厂、造纸厂的轧钢机等，到机床和半导体制造机中使用的机电一体化设备。一种以单片机为主要控制器件，以为。 The motor and its control technology has made considerable progress in recent years.Significant progress in the field of power electronics has brought unprecedented development thanks to the semiconductor technology.Motor drive industry profits have hit various,From large industrial equipment like iron and steel factory, paper mill rolling machines, electromechanical integration equipment used to machine tools and semiconductor manufacturing machine. The general method of driving power of existing high, there are flaws in logic, hardware and software are not coordinated, the control accuracy is not high, the lack of safety monitoring link. The project in view of the above problems focus on the design of a single-chip microcomputer as the main control device, with IGBT as the main power switch device. Design of multi-function MCU motor control system is introduced from two aspects of hardware and software. Describes the design and implementation of the working principle, system. Realization of communication, composed of single-chip encoder, DC power supply, LCD display, to achieve the control of various motor drive. PID can realize speed regulation of motor, and has the undervoltage overvoltage and overcurrent protection. Keywords: communication, drive control, PID motor speed control, protection 目 录 1 前言 1 2 系统的设计及指标 2 2.1 系统设计方案及论证 2 2.1.1 系统设计方案 2 2.1.2 控制器模块设计方案 3 2.1.3 电机驱动模块设计方案 3 2.1.4 速度采集模块设计方案 4 2.1.5 键盘模块设计方案 4 2.2 系统技术指标 5 3 硬件电路设计 6 3.1 单片机模块 6 3.1.1 STC12C5A60S2单片机的基本特性 6 3.1.2双单片机工作模式 10 3.1.3并行通信与串行通信 10 3.2电机驱动电路 11 3.2.1 M57957L的结构 12 3.2.2 M57957L的工作原理 13 3.3 显示电路设计 13 3.4 键盘电路设计 14 4 软件设计 15 4.1 程序流程 15 4.1.1 主流程图 15 4.1.2显示程序流程 17 4.1.3键盘程序程序流程 17 4.2算法实现 19 4.2.1 电机速度算法 19 4.2.2 PID算法 19 小结 20 参考文献 21 附录 部分源程序 22 1 前言 一个多世纪以来，电动机作为机电能量转换装置，其应用范围已遍及国民经济的各个领域以及人们的日常生活中。尤其是
