PLC in the threephase asynchronous motor control applications, with traditional relay control, pared with a control speed, high reliability, flexibility, functional, etc., for a variety of automated control equipment provides a very reliable control is able to provide safe and reliable automation and control applications and more plete solution for the current demand for automation of industrial enterprises. Currently, the electric drive is the industry39。s main drag production machinery forms。 therefore, threephase asynchronous motor has been widely used in all walks of life and daily life and other constantly updated production machinery and development of the motor rotation speed performance issues with increasingly high asynchronous motor threephase asynchronous motors because of its low cost, simple structure, high reliability and low maintenance, etc. in various industrial areas has been widely used, but its speed performance and rotation properties are not as DC motors, so how to improve the performance of asynchronous motor speed and rotation issues in order to improve the speed performance and the corner problem, it is especially important. This article through the squirrelcage induction motor work process analysis, focusing on the threephase asynchronous motor speed and angle performance, try a simple and effective method for speed and angle adjustment. Keywords： PLC， Threephase asynchronous motor， speed， turn angle 目錄 III 目 錄 第一章 緒論 .......................................................................................... 1 三相異步電動(dòng)機(jī) ........................................................................................... 1 三相異步電動(dòng)機(jī)的結(jié)構(gòu)與工作原理 .................................................. 1 PLC 技術(shù) ........................................................................................................ 7 的發(fā)展歷史 ................................................................................... 7 的基本結(jié)構(gòu) ................................................................................... 8 西門子 S7200 系列 PLC .................................................................... 9 變頻器 ......................................................................................................... 10 變頻器基本原理 ................................................................................ 11 變頻器調(diào)速基本原理 ........................................................................ 12 人機(jī)交互界面與西門 子 Smartline ............................................................. 13 人機(jī)交互界面 .................................................................................... 13 西門子 Smartline ............................................................................... 14 第二章 PLC 編程軟件與 HMI 組態(tài)軟件 ........................................... 15 STEP7Micro/WIN ...................................................................................... 15 軟件介紹 ............................................................................................ 15 程序組織 .......................................................................................... 15 程序編輯要點(diǎn) .................................................................................... 15 監(jiān)控 ............................................................................................. 15 wincc flexible 組態(tài)軟件 .............................................................................. 16 wincc flexible 簡介 ............................................................................. 16 wincc flexible 的組件 ......................................................................... 17 第三章 電動(dòng)機(jī)轉(zhuǎn)速控制 .................................................................................. 18 系 統(tǒng)設(shè)計(jì)的總體思路 .................................................................................. 18 變頻器參數(shù)設(shè)置 .......................................................................................... 18 轉(zhuǎn)速控制外部硬件連接圖 .......................................................................... 19 PLC 程序設(shè)計(jì) .............................................................................................. 19 PID 算法 .............................................................................................. 19 2020 屆本科畢業(yè)設(shè)計(jì)論文 IV 內(nèi)存變量分配表 ................................................................................. 20 速度反饋設(shè)計(jì) ..................................................................................... 21 調(diào)試與數(shù)據(jù)分析 .......................................................................................... 21 PID 參數(shù)整定 ...................................................................................... 21 運(yùn)行結(jié)果 ............................................................................................. 22 第四章 電機(jī)轉(zhuǎn)角控制 ....................................................................................... 25 系統(tǒng)設(shè)計(jì)的總體思路 .................................................................................. 25 變頻器參數(shù)設(shè)置 .................................................................................
