Abstract

Eigenspace and linear quadratic techniques are used to design an active flutter suppression system for the DAST ARW-i flight test vehicle. Outboard and inboard control surfaces are included in the design. Flutter controllers that meet control surface activity specifications and provide some gust load alleviation are developed using both eigejispace and linear quadratic techniques. However, inclusion of the inboard control surface is shown to yield substantial design compromises in terms of closed-loop actuator response in the case of linear quadratic design and stability margins in the case of eigenspace design.
