第十一届“挑战杯”辽宁省大学生课外学术科技作品竞赛多功能电机驱动系统的设计研究摘要电机本体及其控制技术在近几年取得相当大的进步。这要归功于半导体技术的空前发展带来的电力电子学领域的显著进步。电机驱动产业发展的利处已经触及各种各样的设备，从大型工业设备像钢铁制造厂、造纸厂的轧钢机等，到机床和半导体制造机中使用的机电一体化设备。现有的一般驱动方法功耗高,有逻辑缺陷,软硬件不协调，控制精度不高，缺少安全监控环节。项目针对以上问题重点设计一种以单片机为主要控制器件，以IGBT为主要功率开关器件。从硬件和软件两方面介绍了单片机多功能电机控制系统的设计思路。阐述了系统的工作原理、设计及实现。由单片机实现双机通信，测速发电机测速，直流供电，LCD显示，实现了对多种电机的控制驱动。可以实现对电机的PID调速，并且具有欠电压过电压过电流保护。关键词：双机通信、控制驱动、电机PID调速、保护AbstractThemotoranditscontroltechnologyhasmadeconsiderableprogressinrecentyears.Significantprogressinthefieldofpowerelectronicshasbroughtunprecedenteddevelopmentthankstothesemiconductortechnology.Motordriveindustryprofitshavehitvarious,Fromlargeindustrialequipmentlikeironandsteelfactory,papermillrollingmachines,electromechanicalintegrationequipmentusedtomachinetoolsandsemiconductormanufacturingmachine.Thegeneralmethodofdrivingpowerofexistinghigh,thereareflawsinlogic,hardwareandsoftwarearenotcoordinated,thecontrolaccuracyisnothigh,thelackofsafetymonitoringlink.Theprojectinviewoftheaboveproblemsfocusonthedesignofasingle-chipmicrocomputerasthemaincontroldevice,withIGBTasthemainpowerswitchdevice.Designofmulti-functionMCUmotorcontrolsystemisintroducedfromtwoaspectsofhardwareandsoftware.Describesthedesignandimplementationoftheworkingprinciple,system.Realizationofcommunication,composedofsingle-chipencoder,DCpowersupply,LCDdisplay,toachievethecontrolofvariousmotordrive.PIDcanrealizespeedregulationofmotor,andhastheundervoltageovervoltageandovercurrentprotection.Keywords:communication,drivecontrol,PIDmotorspeedcontrol,protection目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc352616184"1前言PAGEREF_Toc352616184\h1HYPERLINK\l"_Toc352616185"2系统的设计及指标PAGEREF_Toc352616185\h2HYPERLINK\l"_Toc352616186"2.1系统设计方案及论证PAGEREF_Toc352616186\h2HYPERLINK\l"_Toc352616187"2.1.1系统设计方案PAGEREF_Toc352616187\h2HYPERLINK\l"_Toc352616188"2.1.2控制器模块设计方案PAGEREF_Toc352616188\h3HYPERLINK\l"_Toc352616189"2.1.3电机驱动模块设计方案PAGEREF_Toc352616189\h3HYPERLINK\l"_Toc3526
