Supplemental material for Blade Pitch Control for Floating Wind Turbines: Design and Experiments Using a Scale Model, N. Hara, Y. Nihei, K. Iijima, and K. Konishi, in Proc. the 1st IEEE Conference on Control Technology and Applications (CCTA 2017)
Section IV, Condition A (step wind)
Case 1. No Control (fixed pitch)
You can see the large platform pitch motion after the step wind change occurs.
Case 2: H infinity LSDP
In this case, only small change in platform pitch motion is observed.
