How to setup FAST s-function for individual pitch control purpose

Dear all,

I have a question regarding how to couple an individual pitch controller implemented in Matlab/Simulink with the FAST v7 s-function.
Currently, I found out all the 3 blade pitch angles are combine to one input signal and sent to FAST v7 s-function (See the attached figure). This is exactly the need for the collective pitch controller. But the question is how to input the 3 blade pitch angles separately to the FAST v7 s-function in order to achieve IPC control?

Can anyone help me on this question?

thank you very much in advance.

Best regards

Dear Fanzhong Meng,

In the Simulink interface for FAST v7 (and FAST v8) while the blade-pitch angles are grouped together, you must specify distinct pitch angles for each blade separately (even if all of the angles are same, for a collective blade-pitch controller). So, the S-Function is directly set-up to support individual blade-pitch control (IPC).

Best regards,

Dear Jason,

Thank you very much.
Initially, I also thought like this and just want to make sure I am right.
So now your answer solves the problem.

Thanks again.

Best regards
