Abstract

The research undertaken in this paper implements Multiple-input Multiple-output Active Aeroelastic Control, on a flexible wing system. Two separate configurations of the wing are investigated: 1) The linear case, where the MIMO adaptation of the Receptance Method is implemented to achieve pole-place...
