Abstract
AbstractThis paper presents the robust multi-objective design of a lateral feedforward control law for a large flexible blended wing body (BWB) type passenger aircraft. A multitude of both time- and frequency-domain design constraints are considered to achieve manoeuvre loads alleviation and the desired tracking performance. A convex multi-model feedforward control design is utilized. Scheduled and fixed control laws are obtained and numerically validated and compared on several mass cases of the aircraft model, showing high loads alleviation performance while obeying all stringent design constraints. The benefit of scheduling for a fuel mass parameter is demonstrated.
