The ongoing development of gust detection systems based on a Doppler lidar sensor has created the opportunity to design powerful gust load alleviation controllers with access to the wind field over 100 m ahead of the aircraft. The present paper describes a highly representative public benchmark for lidar-based gust load alleviation. It is based on a linear aeroservoelastic model of the Common Research Model (CRM), a surrogate model of a Doppler wind lidar sensor, and a wind reconstruction algorithm. An active gust load alleviation control design challenge based on this benchmark is proposed, and an example of a lidar-based controller is designed and evaluated against this challenge.
