Active gust load alleviation of high-aspect ratio flexible wing aircraft

This paper presents a novel active gust load alleviation approach within a multi-objective flight control framework developed by NASA for a flexible wing aircraft. The aircraft model is based on the NASA Generic Transport Model (GTM). The wing structures incorporate an aerodynamic control surface known as the Variable Camber Continuous...

Database building and interpolation for a safe flight envelope prediction system

This paper reports the latest progress in the development of a database-driven safe flight envelope prediction system. By building up a database containing safe flight envelopes of different damage and fault scenarios, the challenges associated with online flight envelope prediction can be circumvented. The database is designed for different...

Machine Learning for Flapping Wing Flight Control

Flight control of Flapping Wing Micro Air Vehicles is challenging, because of their complex dynamics and variability due to manufacturing inconsistencies. Machine Learning algorithms can be used to tackle these challenges. A Policy Gradient algorithm is used to tune the gains of a Proportional-Integral controller using Reinforcement Learning. A...

Database-driven Safe Flight Envelope Protection for Impaired Aircraft

In this paper, an online flight envelope protection system is developed and implemented on impaired aircraft with structural damage. The whole protection system is designed to be a closed-loop of several sub-systems, including system identification, damage classification, flight-envelope prediction and fault-tolerant control. Based on the...
