毕业设计(论文)中文摘要
利用单片机控制技术和变频器直接转矩控制原理对矿井提升机运行过程进行控制,具有控制系统安全可靠、动态性能好、响应速度快、加载精度高、节能效果好等特点,对现有矿井提升机的改进及设计高性能的矿井提升设备提供有效的途径。本项目采用变频控制技术、结合单片机控制原理(即运用数字信号处理器这种可编程的单片机,选取专用电机芯片TMS320F240, 利用变频器中的逆变器的脉冲宽度调节(PWM)输出方式控制电机的控制从而控制整个提升机的运作)对提升机交流拖动系统运行过程进行控制,在加速和爬行阶段实行变频控制,当矿井提升机处于减速下落过程中,采用带测速负反馈的闭环系统,,并为矿井的设计提供一个新的思路和更广阔的研究空间。

Title:Hoist operation process exchange VVVF drive system design
Abstract:
SCM control technology and direct torque converter control principle of mine hoist operation process control, control system is safe and reliable, dynamic performance and fast response, high accuracy load, the effect of energy-saving features of the existing mine hoist improvements and the design of high-performance shaft to upgrade equipment to provide effective project uses the frequency control technology microcontroller control principle (that is, use of digital signal processor such programmable microcontroller, Motor selection dedicated chip TMS320F240 The converter using inverter pulse width modulation (PWM) control of the electrical output of the control so as to control the entire reference or machine operation) to enhance the exchange of machine drive system operation process control, and the crawling stage to accelerate implementation of frequency control, When the mine hoist the whereabouts of the slowdown in the process, using guns with the negative feedback loop system, use of Direct Torque Control technology to enhance Moment mechanism for automatic adjustment.
The project study for the mine hoist control System Design and Performance Analysis lay the theoretical foundation, and the mine design a new way of thinking and a broader research in space..
