The complex vertical takeoff and landing conflgurations currently under development necessitate flight control system design that enables substantial reductions of pilot workload through simpli ed vehicle operations. This paper shows optimization and simulation of such a flight control system architecture for a subscale vectored thrust aircraft conflguration. A full-envelope trajectory control system for longitudinal dynamics was coupled with explicit model-following inner-loop controllers and a scheduled control allocation logic. Control system parameters were determined using a genetic algorithm optimization scheme subject to dynamic stability, robustness, and control responsiveness constraints. Flight simulation results for a series of representative maneuvers including departure and arrival transitions and forward ight maneuvers are presented to demonstrate the effectiveness of the proposed flight control system architecture.
