Matlab-RTW实时仿真与嵌入式系统开发-史维佳

Matlab/RTWu给出一种开发嵌入式系统的新方法主要基于Matlab的RTW(Rea-lTimeWorkshop)工具箱的代码生成功能,采用Keil作为中间工具,将RTW生成的C语言代码转换为单片机可以运行的HEX文件,并利用Proteus软件进行仿真,以验证代码的正确性,从而快速开发嵌入式系统,并且实现了实时仿真测试结果验证了该方法的可行性与正确性Matlab/RTWKeilProteus快速原型法实时仿真嵌入式系统112,,,,Matlab/RTW2:,sMicrosoftWindowsXPSP3;2sMatlabVersion7.5.0.342(R2007b);2sKeiluVersion2V2.30;sProteus7.1SP2Matlab/RTW(CRTW(Rea-lStoptimeTypeInfTimeSolverFixed-step),KeilSolverOde5(Dormand-Prince)Matlab,DevicevendorIntelHardwareImplementationDevicetype8051CompatibleCSystemtargetfileErt.tlcHEX,Rea-lTimeWorkshopMake_rtwoptimized_floating_point=1ProteusMakecommand,,,Matlab_TestRea-lTimeWork-1shopBuild,Matlab1Matlab:###StartingRea-lTimeWorkshopbuildprocedureformodel:,2Matlab_Test12,,,,1Simulink,###SuccessfulcompletionofRea-lTimeWorkshopbuildproce-12,,dureformodel:Matlab_Test2,42200910adv@mesnet.com.cn()32rtmSetErrorStatus(Matlab_Test_M,"Overrun");RTWMatlab_Test_TLC(TgtLn-U.In1=P1_6;/Matlab_Test_rt_OneStep/*Stmodlinutsh*guageComil,)TLCU.In2=P1_7;ert_main.c/*Getmodeloutputshere*/P1_0=atlab_Test_Y.Out133int_Tmin(int_Targc,constch_T*argv[])intmain(void)rt_OneStep(),SimulinkTLCmin/*Initializemodel*/Printf(*****);3Cfflush(NULL);,,,HEXRTW,KeilErt.tlcProteus\ModelVDM51.dllRTW:Kil\C51\INC,¹Min,ert_main.c,,TOOLS.INI,VDM51.DLL,4ºMtlab_Test_initiliz,Min»rt_OneSt,MinMatlab_Test.c,,ert_main.c,,,Mtlb_Test_step¼Mtlb_Tst_st,rt_OnStMtlb_Test.c,,/Mtlb_Test_Y.Out1=Mtlb_Test_U.In1+Matlab_Tst_U.In2;0,RTW:Mtlb_Test_U.In1Mtlb_Test_Y.Out1¹Mtlb_Test_U,,ºMtlb_Test_Y,,3KeilKeilKeil4,AtmelcAT89C51,CPU,ert_,KeilKil,ProtusProteusMtlb*.c:1,min.cMatlab_Test.,;*.hProteusVSMMo-Mtlab_Test.hMatlab_Test_nito-51,Keil5vit.hMtlb_Tst_tys.hrtwtypes.hProtus320091043@mesnet.com.cn()Microcontrollers&EmbeddedSystmsDebug,,UseRemoteDebugMonitor80C51,,ProgramFileKeilHEX(Keil_Test.HEX),5,Matlab¹Proteus,Matlab;º»Matlab,,5;,Proteus,P1.0,80C51,;,P1.6P1.7,6[1][2][3][4][5].Matlab/Simulink,1999.[M].:.[M].:,2003.,,,.Matlab/Simulink,2008.[M].:,.Matlab6.5[M].:,2003.,.Matlab[M].:,2008.何鹏举(博士后副教授),研究方向为网络化智能传感器;史维佳李杰(本科)(收稿日期:2009-05-11)6Rea-ltimeSimulationandEmbeddedSystemDevelopmentBasedonMatlab/RTWNorthwesternPolytechnicalUniversityAnewmethodisproposedtodevelopanembeddedsystem.PrimarilybasedonthecodegenerationfunctionofMatlabRTW(Rea-lTimeWorkshop)toolbox,withtheKeilsoftwareasanintermediatetool,itcanchangetheCcodecreatedbyRTWtotheHEXfilethatMCUuses.Proteusisusedassimulationtooltoverifycodecorrectness;therefore,theembeddedsystemdevelopmentandrea-ltimesimulationprocessesarequickened.Thetestverified
