Tower fore-aft damping

Hello Dear Jason, please, I have questions about the Tower fore-aft controller. Which parameters represents the he tower fore-aft bending moment? I use the Parameter YawBrTAxp as the fore-aft acceleration. I want to use a second-order filter between the fore-aft acceleration and the Loop Gain, Pleas...

Re: Problem running Test18.fst in Simulink by Changing TMax using FAST_8.16

Hello Dera Jason, after the Linearization with: TwFADOF1 = True, DrTrDOF = True, RotSpeed =12.1, PCMode = 0, VSContrl=1; Windtype = 1 with HWindSpeed=12m/s. I get the following Matrix: AMat = 0 0 1 0 0 0 0 1 -4.234 0.03072 -0.3436 0.8568 -0.0006466 0.0007049 -0.02692 -0.06755 From AMat: -[M^1]*K = [...

Re: Problem running Test18.fst in Simulink by Changing TMax using FAST_8.16

Dear Jason,

I found the document. Please how can I determine the paramter M, D, K and F of the second order system ?. You told me that it is not possible with FAST v8.
Is the output "TTDspFA" the tower fore-aft velocity?

best regards

Re: Problem running Test18.fst in Simulink by Changing TMax using FAST_8.16

Hello Dear Jason,

Please, do you know what Degrees of Freedom can I set in ELastoDyn.dat to modell a Active tower damping controller?
I set In SerDyn.dat CompNTMD and ComTTMD to True to use ServoDyn_TMD.dat.

Thank you in advance,

best regard,
david

How to find the paramter of the first bending modal mass, damping, and stiffnees coefficients?

Hello, I want to implement a Active tower and Drive Damping Controller. I would like to know how to find the parameters after the Linearization? I've read that just the tower force-aft mode(TwFADOF1) Is to be activated, and all other DOF on false (inactive). I have made the following setting in Inpu...
