Multi-agent control of airplane wing stability under the flexural torsion flutter
This paper proposes a novel method for prevention of the increasing
oscillation of an aircraft wing under the flexural torsion flutter. The paper
introduces the novel multi-agent method for control of an aircraft wing,
assuming that the wing surface consists of controlled 'feathers' (agents).
Theoretical evaluation of the approach demonstrates its high ability to prevent
flexural-torsional vibrations of an aircraft. Our model expands the
possibilities for damping the wing oscillations, which potentially allows an
increase in aircraft speed without misgiving of flutter. The study shows that
the main limitation is the time, during which the system is able to damp
vibrations to a safe level and keep them. The relevance of this indicator is
important because of the rather fast process of increasing wing oscillations
during flutter. In this paper, we suggest a new method for controlling an
aircraft wing, with the use of which it becomes theoretically possible to
increase the maximum flight speed of an aircraft without flutter occurrence. A
mathematical model of the bending-torsional vibrations of an airplane wing with
controlled feathers on its surface is presented. Based on the Speed-Gradient
method a new control laws are synthesized.Comment: 21 pages, 4 figure
