Receptance Based Control of Aeroelastic Systems for Flutter Suppression

McDonough, Laura

Abstract Details

2012, Master of Science, Miami University, Computational Science and Engineering.
The field of aeroelasticity deals with mutual interaction between inertial, elastic, and aerodynamic properties of a flexible system. Aeroelastic instabilities, such as flutter, can lead to fatigue and potential failure of an aerospace structure. Active control strategies may be needed to avoid such instabilities to achieve increased flight performance. In this research, receptance based active control schemes are developed for flutter suppression and flutter-boundary extension. In principle, this method utilizes receptance frequency response functions extracted from embedded sensors and actuators of the aircraft, representing the true aeroelastic interaction, for control force computations. Hence, it circumvents potential modeling errors associated with structural and aerodynamic parameters, which are used in traditional state-space based aeroelastic control. In this study, receptance based single input, multiple input and output state feedback control is developed. Several aspects of control design including actuator dynamics, optimization and robustness are demonstrated through numerical simulations and computational studies.
