Active simulation of time histories of strong wind gust in a wind tunnel

Abstract This paper describes an active simulating procedure of the time history of wind velocity in a wind tunnel. The simulated time histories of the wind velocity by this technique fitted well the target ones. The wind gust observed at the site was simulated. The step changing wind gusts which wind velocity changes in a short time were generated. The simulated time histories of wind velocity were repeatedly reproduced. The advantages of active simulation are summarized.
