the coupling of the pitch control and torque control

This forum if for discussing controls. Questions about how to implement controls in FAST are more appropriate to the CAE Tools forum.

the coupling of the pitch control and torque control

Postby Ruiliang.Wang » Tue May 17, 2016 6:51 am

hello everyone,
when the wind speed get the rated value with the turbulence,the wind speed will vary around the rated,while the control system will switch between the torque control and pitch control,around the rated the fluctuation of power and load is large.
I want to know how to make the transition of controls more smoothly.Do you have some methods to deal with the coupling of the control systems and make the system more stable?
Best Regard!

Hello, I am a PhD student from Spain. I have the same doubt.

Would it be interesting to decouple the Power generated - pitch control loop and angular velocity wg - torque control loop?

Best regards.

Manuel Lara.

Dear Ruiliang and Manuel,

While I'm not expert, NREL's Reference OpenSource Controller (ROSCO) for wind turbine applications may be of interest to you: https://github.com/NREL/ROSCO.
