Hardware in the loop

[Jason.Jonkman]

Dear Sina,

My understanding is that there are options in MATLAB/Simulink for running real-time simulations, but I’m not very familiar with these. If your existing FAST / OpenFAST model within MATLAB/Simulink already runs faster than real time (or can be simplified a bit to do so), I would guess it would possible to use it for real-time applications, but you’d have to check MATLAB/Simulink documentation for information on how to do that.

A similar question was discussed in the following forum topics, but I’m not sure where the work ended up:

FAST8 Build Model problems

I don’t have any experience building Simulink models for real-time simulation. I have read some comments about it in the MATLAB/Simulink documentation that I sent you. I do not think you have to modify the header file; I think you need to make sure MATLAB is setting the appropriate preprocessor flags so it uses the correct header files. My concern is that your error message seems to indicate that Matlab is finding duplicate header files, some of which are in the real-time-workshop toolbox. The …

Error by Building FASTv8 in Simulink External mode

Hi, David. I am not very familiar with Simulink’s external mode. FAST_SFunc is normally compiled as a mex function (dynamic library) with the create_FAST_SFunc.m script found in the FAST archive. OpenLoop.m will call the already-compiled mex function. The FAST v8 ReadMefile has a section explaining the FAST-Simulink interface. From what I have read about Simulink’s external mode, you need to create a target application from your Simulink model. This target application would need to include th…

The FAST v7 interface to LabView was used for real-time implementation, but this functionality has not yet been ported to FAST v8 or OpenFAST. It was up to the user to set up the FAST v7 model so that it would run faster than real time without the interface to LabView enabled. LabView would then wait before calling FAST v7 again so that the simulation was real time. NREL used the LabView interface to link FAST v7 with the actual controller implemented on the physical CART wind turbine tested at NREL (in a hardware in the loop mode), so that the controller could be tested before using it on the real CART. This capability is discussed a bit in the following forum topic:

Hardware-in-the-loop simulation ( Labview / NI)

Hello, I read the document “Using FAST for LabVIEW.pdf” and I would like to buy suitable equipment for real-time aerogenerator closed loop control, I intend use Hardware In Loop for do my simulation tests and control studies. On page 1 of the document is written that were used PXI Controllers for simulation of turbines CART. I would like to know what NI hardware(PXI controller) was used. Could you help me with this? Also would like to know if the hardware was able to meet the requirements of …
