Robust autopilot design for crosswind landing

A comprehensive autolanding design for the representative model of a twin-engined commercial aircraft is presented in this paper. A cascaded structure is selected to facilitate the design task and to minimize control law switching. Classical loopshaping and robust control techniques are used to design the individual control loops. The emphasis is on design parameters with a clear relation to design objectives, resulting in an intuitive tuning procedure. The control system's ability to safely land the aircraft despite strong crosswind in a variety of possible scenarios is demonstrated in an industry-grade verification campaign. Monte Carlo simulations are used to assess the risk of unsafe landing conditions and provide insight into the performance characteristics and limitations of the proposed control system.
