This chapter focuses on basis of active flutter suppression systems. For rendering a flutter suppression system robust to even the large modelling uncertainties of the transonic regime, adaptive control laws are explored. Subsonic single degree of freedom (d.o.f.) flutter involving attached flows, due to its second‐order dynamics, can be prevented either by the passive means of increasing the torsional stiffness of the wing and/or the control surface, or by placing high‐gain, linear filters in a feedback control loop. Owing to the inherent uncertainty in the aerodynamic parameters, an adaptive control loop must be added to suppress both linear and nonlinear s.d.o.f. flutter. A linear feedback controller can be designed in the ideal case using the traditional methods for a given flight condition. Three‐dimensional wings can experience multi‐mode flutter due to the aeroelastic coupling between several structural modes and unsteady aerodynamic loads.
