Running ROSCO on Simulink

[EhsanASL92]

Hi, I am trying to run ROSCO on Simulink. First, I added the ROSCO_toolbox to set the path in Matlab. Then, I changed the directory name for the SFunction and FAST directory. fast.FAST_SFuncDir = 'D:\OpenFASTbyEhsan\openfast-3.1.0\glue-codes\simulink\src'; %%%% NEED FOR SIMULINK fast.FAST_InputFile = '5MW_Land_BD_DLL_WTurb.fst'; % FAST input file (ext=.fst) fast.FAST_directory = 'D:\OpenFASTbyEhsan\openfast-3.1.0\reg_tests\r-test\glue-codes\openfast\5MW_Land_BD_DLL_WTurb'; % Path to fst directory files I tested it with both FAST v8 and OpenFAST v3.1.0 But I see this error : Error in ReadWrite_FAST (line 14) FP = FAST2Matlab(fullfile(fast.FAST_directory,fast.FAST_InputFile),2); %FP are Fast Parameters, specify 2 lines of header (FAST 8) Can you help me with running ROSCO on Matlab/Simulink?

I run OpenFAST examples and they all run properly!

Hi,

We can't properly test these simulink examples, so we can't support them quite as well. Can you place a breakpoint deeper into ReadWrite_FAST to understand the issue it has?

Thanks for your reply @dzalkind, In fact, I just tried to run the ROSCO controller. Based on what I see on the running guide, it cannot be hard to run. I just defined some directories and then tried to use runFAST.m. This is the first step for running ROSCO, but do not know why I see such an error! I have attached the required files here.

ReadWrite_FAST.zip runFAST.zip

Please post the error that ReadWrite_FAST has. Also, I encourage you to find a solution here because we cannot support Simulink issues at this time.

Here is the error

**Unrecognized function or variable 'FAST2Matlab'.

Error in ReadWrite_FAST (line 14) FP = FAST2Matlab(fullfile(fast.FAST_directory,fast.FAST_InputFile),2); %FP are Fast Parameters, specify 2 lines of header (FAST 8)

Error in runFAST (line 29) [Param,Cx] = ReadWrite_FAST(fast);**

I check both github and also the NREL forum, but cannot get a good response for that yet!

[dzalkind]

Have you tried searching for that function and adding it to your matlab path?

[dzalkind]

Please see the documentation here: https://github.com/NREL/ROSCO/tree/main/Matlab_Toolbox

You need the OpenFAST matlab-toolbox.

[EhsanASL92]

Yes, I have already run the OpenFAST v3.1.0 and it is running correctly. I also added all the necessary paths to my environment.

I have encountered the same problem as you. Make sure the Matlab-toolbox folder path is added to the Matlab path.
