Abstract :
A numerical investigation of instability of an aeroelastic model subjected to an external disturbance is carried out with pitch, plunge and flap motions. The uncontrolled response of a model is very dangerous and catastrophic in nature. To control the dynamics, the linear quadratic regulator (LQR) a form of feedback control methodology is used in conjunction with a neural network as a state-observer to estimate the parameters to control the model. The controller performance is studied against the conventional LQR control. Time-domain simulations are conducted near the flutter regions. Results are shown in the form of graphs and tables.
