Dear All
At the moment, I have obtained a state space model of one blade. I would like to try some control method on it but I need to do use some disturbance. I am wondering how could I use TurbSim to generate the turbulence because the turbulence generated by TurbSim is usually for a wind turbine not for one blade. Except TurbSim, I am wondering if there is any other tools that I can use to generate turbulence for one blade? what kind of disturbance would you use to test a blade usually?
The state space model has 10 inputs for disturbance and it physically means the 10 points along the blade distributed evenly.

Dear Xing,
I’m not sure I know enough about what you are doing to comment. TurbSim is a generic model for generating time realizations of given turbulence conditions, so, I’m sure you can use it to excite your model. Of course, I’m not sure you’re model includes aerodynamic theory, but you’ll have to obviously determine how the turbulent wind induces aerodynamic loads. Alternatively, you could excite your blade with step changes in wind/aerodynamic loads or white noise.
Best regards,
Dear Jason
Thank you for your reply. The aerodynamic theory I used is vortex panel method and the disturbance input are actually the angle of attack of every point. I am wondering what is the usual method to test one blade? Turbulence or gust or anything else? If it is turbulence, is there any other tools except TurbSim?

Dear Xing,
I think steps, impulses, turbulence, and white noise are common approaches to excite a structure. TurbSim is the turbulence tool provided by NREL.
