基于单片机的直流调速系统系统设计DesignofDCSpeedRegulationSystemBasedonSingleChipMicrocomputer摘要本文的主题是单芯片微型计算机的DC速度控制系统的设计。早期直流电机的控制策略包含模拟电路、数字电路以及运算放大器等等。当前随着科学技术的快速发展，直流电机的控制策略也随之逐渐发展，已经实现了控制系统的数字化应用，直流电动机控制方式从模拟电路向数字电路的转换，特别是单芯片技术的应用提供了新的控制思路。直流电动机的速度控制系统的优点是高的起动性。在很多需要快速反应调速的领域中，都有它的一席之地。在当今的电子产品里面，直流电机调速系统得到了广泛地应用。AT89S52单片机是本文的设计核心，我将通过两个方面完成此次系统的设计与调试，分别是单片机和C语言。科技越来越发达，单片机性能越来越好，有多种算法来控制不同种类的单片机，多种算法与控制的结合下产生了极高的灵活性与可操作性，高性能的系统也是越来越多。我通过单片机的操作系统，减少了很多人力与金钱的成本，有效地提高了效率。关键词：AT89S52单片机，控制系统，直流调速AbstractThethemeofthispaperisthedesignofDCspeedcontrolsystemforsinglechipmicrocomputer.EarlyDCmotorcontrolstrategiesincludeanalogcircuits,digitalcircuitsandoperationalamplifiers.Atpresent,withtherapiddevelopmentofscienceandtechnology,thecontrolstrategyofDCmotorhasbeengraduallydeveloped.Thedigitalapplicationofcontrolsystemhasbeenrealized.TheconversionofDCmotorcontrolmodefromanalogcircuittodigitalcircuit,especiallytheapplicationofsinglechiptechnology,providesanewcontrolidea.ThespeedcontrolsystemofDCmotorhastheadvantageofhighstartup.Inmanyareasrequiringrapidresponsespeedregulation,ithasitsplace.Intoday'selectronicproducts,DCmotorspeedcontrolsystemhasbeenwidelyused.AT89S52singlechipcomputeristhedesigncoreofthispaper.Iwillcompletethedesignanddebuggingofthissystemintwoaspects:singlechipcomputerandClanguage.Withthedevelopmentofscienceandtechnology,theperformanceofsingle-chipcomputerisgettingbetterandbetter.Therearemanyalgorithmstocontroldifferentkindsofsingle-chipcomputer.Thecombinationofvariousalgorithmsandcontrolresultsinhighflexibilityandoperability,andmoreandmorehigh-performancesystems.Throughtheoperationsystemofsinglechipcomputer,Ihavereducedthecostofmanpowerandmoney,andeffectivelyimprovedtheefficiency.Keywords:AT89S52SingleChipMicrocomputer,Controlsystem,DCspeedregulation目录第1章绪论...............................................................................................................................51.1课题背景及意义...........................................................................................................51.2直流电机调速原理.......................................................................................................61.3系统方案与分析...........................................................................................................71.4总体硬件电路设计.......................................................................................................8第2章PWM脉宽调制原理.....................................................................................................82.1PWM调速原理............................................................................................................82.2PWM调速方法............................................................................................................92.3PWM实现方式............................................................................................................9第3章硬件部分...
