Novel approaches for longitudinal control laws of commercial aircraft

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. If successful, those techniques will allow to improve the control laws robustness and performance. They will also offer a major competitive advantage by significantly reducing design turnaround times and the needs for exhaustive development flight test.
