Control Law Design for Perching an Agile MAV with Articulated Wings
This paper explores the use of variable wing dihedral and variable wing twist (in conjunction
with a conventional horizontal elevator) to control an aircraft performing a perching
maneuver. A choice of controller architecture wherein the dihedral is employed in the
forward path and the elevator and twist are employed in the feedback path, is considered.
The aircraft is modeled as a multivariable linear time-varying system. A specific perching
trajectory is considered; and the open-loop aircraft is longitudinally unstable for a segment
of this perching trajectory and lateral-directionally unstable for the entire perching trajectory.
A multivariable time-varying controller is designed to efficiently stabilize the aircraft
as well as reject longitudinal-lateral-directional wind disturbances, while closely tracking
the reference perching trajectory
