Linearization on FAST v7 - Wind input

Wind & Water General

Dear Forum Members,
I´ve been trying to generate state space linear using fast linearization, i get the model but there is something i can not figure it out and i dont know why. Well basically i cant see how to insert the wind as input in the state space model (i´m using simulink) that Fast 7 generates, since in this version the wind only appears as disturbance, can anyone help me?

Thank you very much.

Dear Bruno,

I’m not really sure I understand your question, but in FAST v7, the “input” vector to the linear state-space were separated into “control input” and “wind disturbance” vectors. In FAST v8 and OpenFAST, these are not separated out, but are both elements of the “inputs” vector.

Best regards,
