This paper will introduce you a new suspending push - type convey system which is applied in some special occasions 本文將介紹一種新型的懸式推掛物流傳輸系統(tǒng),適用于某些特定的場合。
This paper bases on the linear - motor - driven suspending push - type convey syetem , and emphasizes the control system and the realization of its control strategy 本文在介紹直線電機(jī)驅(qū)動的懸式推掛物流傳輸系統(tǒng)的基礎(chǔ)上,著重闡述了其控制系統(tǒng)及其控制策略的實現(xiàn)。
Based on the introduced of the main structure of the linear - motor - driven suspending push - type convey system , this paper expatiate the logical control subsystem and driven control subsystem of this convey system 在系統(tǒng)的邏輯控制部分,主要闡述了系統(tǒng)的功能、結(jié)構(gòu)的劃分以及整體的邏輯控制軟件的實現(xiàn)。
First , this paper not only introduces the basic principle , the history , the category and the control of linear motor but also shows the development of the control system and technology of motor . second , the method of pid control and the technology of pulse width modulation are expatiated , as well as their application in linear - motor - driven servo syetem . third , this paper describes the hardware structure including its operation principle of the control system of the dsp based linear - motor - driven suspending push - type convey system 文章首先介紹了直線電機(jī)的基本原理、發(fā)展歷史及其分類方法,并簡單闡述了直線電機(jī)的控制方法;然后介紹了電機(jī)控制系統(tǒng)及技術(shù)的發(fā)展,進(jìn)而分析了pid控制方法和脈寬調(diào)制技術(shù),及其在直線電機(jī)驅(qū)動的伺服系統(tǒng)中的應(yīng)用;接著介紹了基于dsp的直線電機(jī)驅(qū)動的懸式推掛物流傳輸控制系統(tǒng)的硬件結(jié)構(gòu)及其工作原理,并闡述了直線電機(jī)驅(qū)動的懸式推掛物流傳輸系統(tǒng)控制的軟件實現(xiàn),介紹了各個程序模塊以及速度的檢測方案。
