摘要
En 中文
In this work a simple adaptive flutter suppression system is designed in order to increase the operative speed range of a wing-aileron aeroelastic plant. The equivalent beam finite element based aeroelastic modeling of a wing equipped with a trailing edge aileron in incompressible flow is presented and its state space representation is provided. The almost strictly passivity of the plant is assured by means of a parallel feed-forward compensator implementation and the invariant controller parameters are tuned using a population decline swarm optimization algorithm that minimize the integral of the time absolute error on the wing tip torsion angle. The performance of the closed loop system are studied carrying out numerical simulations that reproduce different flight scenarios with the presence of speed variations, disturbances, and gusts proving the effectiveness of the proposed simple adaptive flutter suppression architecture.
