Abstract
This paper proposes a novel method for the unbounded oscillation prevention of an aircraft wing under the flexural torsional flutter, an innovative multiagent attitude to control an aircraft wing with a surface consisting of managed rotating “feathers” (agents). Theoretical evaluation of the method demonstrates its high aptitude to avoid an aircraft wing’s flexural-torsional vibrations via expansion of the model’s ability to dampen the wing oscillations. It potentially allows increasing an aircraft’s speed without misgiving of the flutter. A new way to control an aircraft wing based on the Speed-Gradient methodology is suggested to increase the maximal possible flight speed without a flutter occurrence. Provided experiments demonstrate the theoretical advantage of the multiagent approach to the “feathers” rotation control.

Summary
The paper investigates a critical problem of airplane wing control under the flexural torsional flutter. A novel approach proposed in this paper suggests covering an aircraft wing both above and below with small-sized rotating elements (“feathers”) capable of changing the orientation according to the airflow. Updated information flow within a distributed network is processed, not centrally, but directly at the agents based on their local observations and locally available data from the appropriate neighbors Both resource and time costs of communication are significantly lessened, and the processing and decision-making time in the center (if it does exist). We suppose a mathematical model of the bending-torsional vibrations of an airplane wing with controlled “feathers” on its surface and consider three functionally different statements of the control problem.
