LIDAR-based Gust Alleviation Control System: Obtained Results and Flight Demonstration Plan

Abstract This paper presents a flight demonstration project for LIDAR-based gust alleviation control currently planned in Japan. The onboard coherent Doppler LIDAR has already been developed and validated by flight experiments. The wind velocity estimation algorithm has also been developed which can estimate two-dimensional distribution of wind field between two laser beams of the LIDAR system. These components are to be combined with the preview control law which utilizes the estimated wind velocities in front of the aircraft, and to be proven in the flight demonstration. This paper shows the results obtained so far and introduces the flight demonstration under planning.
