Re: nonlinear state-space model

i need the nonlinear differential equations of the wind turbine for region 3 goals.
But I can not find them.

thanks.

Re: nonlinear state-space model

Thank you very much for your help
Now, my question is, as you say, since non-linear equations of region 3 wind turbines are not specifically available, so can not design nonlinear controllers which require nonlinear dynamics?

Re: nonlinear state-space model

thanks
and So, my question is, a nonlinear relation between the pitch angle and the rotor speed is available?

Re: nonlinear state-space model

theta is the output pitch angle given into the model.
Is it possible to email The nonlinear equations of motion used by FAST to me ?
My work depends heavily on having nonlinear equations of motion and pitch actuator.

thanks for your help.

Re: nonlinear state-space model

Hello thanks for your answer To design a non-linear controller, I must have a nonlinear equation of pitch actuator and blade root bending moment related to the 13th test of FAST8.16. Can you give me them? In fact, I want the nonlinear relation of the attached equation related to the 13th test of FAS...

Re: Linearization of the full system

hello i have a question about linearization.I want to design a PID controller for pitch control. I need to use linearization and must pcmode = 0 in the linearization, but in this mode, the pitch control command is not taken from the simulink and the pitch angles are commanded zero. How can I use pcm...

nonlinear state-space model

hello I want to design a nonlinear individual pitch controller for wind turbine load reduction in my master's thesis, but I don't have the nonlinear state-space model of the 1.5 MW wind turbine available in the FAST test. It is essential for me to have those non-linear equations to design a nonlinea...
