Abstract:	The paper develops an indirect adaptive control for a multi-input multi-output active flutter suppression system adopting an identifier based either on an extended Kalman filter, with adaptive adjustment of the metastate covariance, or on a recursive moving block least squares technique. The related control law is designed by using an eigenstructure assignment method. The controller thus obtained is verified through extensive numerical simulations on a time varying aeroservoelastic model excited by widely varying levels of turbulence. The control system is required to adapt both to slow variations of the system operational parameters, e.g. fuel consumption, slow acceleration manoeuvres; and to fast changes, e.g. store release, violent accelerations. The capability to maintain system stability after an actuator malfunction is also verified. The results demonstrate that the extended Kalman filter is superior to the least squares method in identifying the system. However the overall performances of the adaptive controller are quite insensitive to the identification results, so that the lower computational resources and cost required for the implementation of the least squares identifier makes it a better candidate for a practical realisation.
