Aeroelastic Dynamic Response and Control of an Aeroelastic System with Hysteresis Nonlinearities [PDF]
Journal of Control Science and Engineering, 2015 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.
