A geometry-based analytic attitude estimation using a rate measurement and measurement of a single reference vector has been recently proposed. Because rigid body attitude estimation is a fundamentally nonlinear problem, the geometry-based method does not contain errors consequent to linearization a…
This letter extends recent work on globally asymptotically stable nonlinear attitude control of fully actuated vehicles to underactuated vehicles, specifically, a rudderless fixed-wing airplane. Previous work uses a quaternion attitude representation and Lyapunov theory to establish global asymptoti
A recurring problem in controlling the attitude of miniature/micro aerial vehicles (MAVs) is the presence of an unknown atmospheric wind. Wind directly affects the vehicle's translational variables, namely the airspeed, angle-of-attack, and sideslip angle, all three of which are important variables
