基于單片機(jī)控制的直流電機(jī)調(diào)速系統(tǒng)的設(shè)計(jì)
（作者未知） 2011/4/13
摘要: 詳述了以89C51單片機(jī)作為直流電機(jī)調(diào)速系統(tǒng)的控制核心的結(jié)構(gòu)框圖,對(duì)幾個(gè)主要控制電路進(jìn)行了分析,給出了控制系統(tǒng)的程序流程圖。該系統(tǒng)解決了以往復(fù)雜的模擬電路設(shè)計(jì)問題,增強(qiáng)了對(duì)直流電機(jī)速度的可控性,提高了調(diào)速系統(tǒng)的精度。
關(guān)鍵詞:單片機(jī);控制電路;調(diào)速系統(tǒng)

Abstract: This essay exp licates the block diagram of AC machine timing system with 89C51 singlechip as its core control component, analyzes severalmajor control circuits, and brings forward program flow chart of the control system. This system modifies the p revious comp lexity in designing analog circuit, enhances the controllability of the speed ofAC machine, and increases the precision of the timing system.
Key words: singlechip; control circuit; timing system
