Data-Efficient Deep Reinforcement Learning for Attitude Control of Fixed-Wing UAVs: Field Experiments
Bøhn, Eivind Eigil; Coates, Erlend M.; Reinhardt, Dirk Peter; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)Attitude control of fixed-wing unmanned aerial vehicles (UAVs) is a difficult control problem in part due to uncertain nonlinear dynamics, actuator constraints, and coupled longitudinal and lateral motions. Current ... -
Geometric Reduced-Attitude Control of Fixed-Wing UAVs
Coates, Erlend M.; Fossen, Thor I. (Peer reviewed; Journal article, 2021)This paper presents nonlinear, singularity-free autopilot designs for multivariable reduced-attitude control of fixed-wing aircraft. To control roll and pitch angles, we employ vector coordinates constrained to the unit ... -
Toward Nonlinear Flight Control for Fixed-Wing UAVs: System Architecture, Field Experiments, and Lessons Learned
Coates, Erlend M.; Reinhardt, Dirk Peter; Gryte, Kristoffer; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)Inner-loop control algorithms in state-of-the-art autopilots for fixed-wing unmanned aerial vehicles (UAVs) are typically designed using linear control theory, to operate in relatively conservative flight envelopes. In the ...
