The A220 aircraft, former CSeries, is the first commercial aircraft certified by Bombardier with fully augmented Fly-by-Wire Control Laws. The longitudinal controller gains are usually scheduled across the flight envelope according to relevant aerodynamic variables. Their tuning can be a lengthy and, sometimes, sub-optimal process. Hence, it is key for Airbus Canada to continue developing state-of-the-art design methodologies based on recent academic research. During this Master’s thesis, the student will evaluate the benefits and applicability to A220 of two ways of addressing this topic.
