Abstract

The performance of a robust control strategy applied to a 2-D supersonic flap-wing aeroelastlc system impacted by a pressure pulse in the subcritlcal flight speed regime is analyzed. The study is carrled-out via implementation of the Linear Quadratic Gaussian (LQG) control methodology with sliding mode observer. Its performance toward suppressing flutter and reducing the vibrational level in the subcritical supersonic flight speed range is revealed and pertinent conclusions are outlined.
