Re: (measured) Pitch Angle differs to demanded pitch angle

Hi Jason,

Thanks for the information. The first approach works perfectly for me. Now the commanded and the actual pitch angle is identical.

Best Regards,
Marvin

Hi, I have some trouble with the pitch behavior in openFASTv1. As far as I understand the (measured/actual) pitch angle should be the same as the demanded pitch angle. In my case the actual pitch angle oscillates around the demanded pitch angle. As background knowledge to my problem might be said, t...

I tried to use the avrSwap(107) to define a ramp up of the braking torque. But it doesn't worked, as the Record 107 is not read by the subroutine Retrieve_...
