Abstract EN
A state feedback control law based on the sliding mode control method is derived for the aeroelastic response and flutter suppression of a two-dimensional airfoil section with hysteresis nonlinearity in pitch.
An observer is constructed to estimate the unavailable state variables of the system.
With the control law designed, nonlinear effect of time delay between the control input and actuator is investigated by a numerical approach.
The closed-loop system including the observer and nonlinear controller is asymptotically stable.
The simulation results show that the observer can give precise estimations for the plunge displacement and the velocities in pitch and plunge and that the controller is effective for flutter suppression.
The time delay between the control input and actuator may jeopardize the control performance and cause high-frequency vibrations.
