How to implement an user-defined pitch setting series in openfast?

Open winder365 opened this issue 11 months ago • 1 comments

Dear @jjonkman,

I want to implement an user-defined pitch setting series in openfast. To be more specifically, I want to make the pitch angle of the blades change according to a time-pitch series which defined by the user.

Can I realize this in OpenFAST?

Thank you for your attention!

Best wishes,

Dear @winder365,

If you user-defined pitch angle time series is a simple linear ramp, you can specify the pitch motion directly through the ServoDyn input file via the override pitch maneuver inputs.

If your user-defined pitch angle time series has a more complicated form, you can implement this in OpenFAST, but you'll have to do so through one of the user-specified pitch-control options, such as PCMode = 3 (SUBROUTINE PitchCntrl(), 4 (via Simulink), or 5 (Bladed-style DISCON library).

Best regards,
