ROSCO EKF wind estimator inputs

Wind & Water Controls

Is the OpenFAST ROSCO EKF wind estimator only using generator speed, torque and pitch? This seems to be the case for the Simulink version. I can’t find any documentation explaining the OpenFAST version (Non Simulink). Therefore I would also like a reference to details on the EKF.

Hi Torben,

Those same inputs are used in the Fortran version: ROSCO/rosco/controller/src/ControllerBlocks.f90 at cfda6af95cda15616b840199c24fbd208e63893c · NREL/ROSCO · GitHub

The best text-based reference is in Section 5.1 here: ROSCO/rosco/controller/src/ControllerBlocks.f90 at cfda6af95cda15616b840199c24fbd208e63893c · NREL/ROSCO · GitHub

I hope this helps.

Best, Dan

Dear Dan

Thanks a lot for the very quick response which answered the main question.
However, I think you were so quick that you used the same link twice.

Ah, sorry, here is the correct second link: WES - A reference open-source controller for fixed and floating offshore wind turbines

Thanks, this seems to be a very good paper on the ROSCO controller. I am also happy to see that you found inspiration in my work for the EKF. I had this feeling already from looking into the code.
