레거시함수를사용하여지정되거나상속된샘플시간

모델 열기

이예제에서는레거시코드툴을사용하여레거시C함수를지정,상속,파라미터화된샘플시간과통합하는방법을보여줍니다。

레거시코드툴을사용하면다음이가능합니다。

  • 레거시함수사양제공

  • 시뮬레이션중에레거시코드를호출하는데사용되는C-MEX S-Function생성

  • 생성된S-Function을시뮬레이션용으로컴파일및빌드

레거시함수사양제공하기

레거시코드툴과함께제공되는함수는특정데이터구조체또는구조체로구성된배열을인수로받습니다。데이터구조체는첫번째입력값으로“初始化”를사용하여함수legacy_code()를호출함으로써초기화됩니다。구조체를초기화한후에는통합하려는레거시코드에해당하는값에속성을할당해야합니다。이예제에서호출하는레거시함수의프로토타입은다음과같습니다。

FLT增益标量(const FLT in, const FLT增益)

여기서FLT는浮动형에대한typedef입니다。레거시소스코드는파일your_types.h，gain.h및gainScalar.c에서확할수있습니다。

Defs = [];% sldemo_sfun_st_inheritedDef = legacy_code(“初始化”）;def.SFunctionName =“sldemo_sfun_st_inherited”；def.OutputFcnSpec ='single y1 = gainScalar(single u1, single p1)'；def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};Defs = [Defs;def);% sldemo_sfun_st_fixedDef = legacy_code(“初始化”）;def.SFunctionName =“sldemo_sfun_st_fixed”；def.OutputFcnSpec ='single y1 = gainScalar(single u1, single p1)'；def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};def.SampleTime = [2 1];Defs = [Defs;def);% sldemo_sfun_st_parameterizedDef = legacy_code(“初始化”）;def.SFunctionName =“sldemo_sfun_st_parameterized”；def.OutputFcnSpec ='single y1 = gainScalar(single u1, single p1)'；def.HeaderFiles = {“gain.h”};def.SourceFiles = {“gainScalar.c”};def.IncPaths = {“sldemo_lct_src”};def.SrcPaths = {“sldemo_lct_src”};def.SampleTime =“参数化”；Defs = [Defs;def);

시뮬레이션중에사용할S-Function생성및컴파일하기

함수legacy_code()는입력인수“def”로제공되는설명에따라C-MEX s函数을자동으로생성및컴파일하기위해첫번째입력값을”generate_for_sim으로설정하여다시호출됩니다。이S-Function은시뮬레이션에서레거시함수를호출하는데사용됩니다。S-Function의소스코드는sldemo_sfun_st_inherited.c，sldemo_sfun_st_fixed.c및sldemo_sfun_st_parameterized.c파일에서확할수있습니다。
