“…Flexible aircraft control has become a research topic of high interest over the last decade ( [5], [6], [7], [16], [17]) due to the potential reduction in structural weight. Large lightweight aircraft structures and novel concepts, such as Blended Wing Body (BWB) aircraft configurations, can lead to higher fuel-efficiency and reduced emissions [11].…”

Two LQ-based MIMO controllers (LQG and LQI architectures) for lateral inner loop flight control for a large Blended Wing Body (BWB) passenger aircraft pre-design model are presented. The main control goals are Dutch roll mode damping, coordinated turn, and roll response shaping. An open loop analysis shows that traditional SISO design faces fundamental limitations, so both controller variants are designed as MIMO controllers. Their performance is tuned and evaluated, and their specific properties are discussed and compared. The controllers are validated on various fuel and payload mass cases and fulfill all demanded goals. Ongoing and future research seeks to reduce structural loads and increase passenger comfort using robust control design methods.

“…Control of flexible aircraft is by now a widely studied task (Hanel [2001], Jeanneau et al [2005], , ), driven by potential weight savings and thus potentially increased fuel efficiency. Novel concepts in civil aviation such as blended wing body (BWB) aircraft introduce numerous new challenges to this class of multi-objective control design problems (see Mialon and Hepperle [2005]).…”

This paper presents the robust multi-objective design of a lateral feedback control law for a large flexible blended wing body (BWB) type passenger aircraft. An initial controller is synthesized and optimized using a convex synthesis approach based on the Youla parameterization and an LMI formulation. A multitude of both time-and frequency-domain design constraints are considered aiming to improve disturbance rejection. The obtained control law is numerically validated on several mass cases of the aircraft model, showing high loads alleviation and vibration reduction performance while obeying all stringent design constraints.
