Questions on DISCON DLL from Simulink controller

[hbasbas]

Dear all,

First, thanks to all that share their works on FOWT,

I would like to make the implementation of FOWT controllers from Simulink as you did. I read all the shared codes and I still have few questions :

1. Having read all the discon_main.c code, the TLC file "discon.tlc", the template for the makefile "discon_vc.tmf" and having modified the version of the Simulink file for an R2021a version, I can't find a line of code that goes against a different version of R2022a. Why do we need to keep the 2022a MATLAB version ?
2. I would like to find the location of the external functions such mdlOutputs() ? I have checked in the different header files at the top of the code but impossible to get it.
3. There are only two parameters in « discon_WaveFF.in » but 10 parameters should be obtained from this file based on SetParams() function in discon_main.c. Why ?
4. In the DISCON() function, the generator electrical power input is not available but it is recquired by OpenFAST. How this is dealt ?

Best regards,

Hedi
