where the Blade-type control interface can be found #1839

Closed Tomedssa closed 1 year ago

Tomedssa commented 1 year ago

Hi, I just started to contact OpenFAST, some questions may not be professional, please don't mind. The article "A Reference Open Source Controller for Stationary and floating offshore wind Turbines" mentions that OpenFAST uses a Blade-type control interface to communicate with ROSCO. But I'm not sure where the Blade-type control interface can be found. Can you help me find it? Thank you very much for your time in advance. Tomedssa

Dear @Tomedssa,

I believe you mean that you are asking about the "Bladed-style control interface"; is that correct? the ROSCO controller is implemented as a Bladed-style dynamic library. The ServoDyn module of OpenFAST supports an interface to controllers implemented Bladed-style dynamic library format.

ROSCO is available here: https://github.com/NREL/ROSCO.

Best regards,

Hello jjonkman， Thanks for your reply; I opened a ServoDyn module for OpenFAST. I found the blade interface section in this ServoDyn module,is this the Bladed-style control interface？In other words, am I correct in understanding that OpenFast interacts with ROSCO through blade interface module? Thanks a lot.

Dear @Tomedssa,

Correct. OpenFAST will use the Bladed DLL interface when PCMode =5 (for pitch control), VSContrl = 5 (for torque control), HSSBrMode = 5 (for control of the brake), YCMode = 5 (for yaw control), AfCmode = 5 (for airfoil control), and/or CCmode = 5 (for cable control).

Best regards,
