The performance of an adaptive flutter suppression system (AFSS) was demonstrated on a flutter model in a wind tunnel. The AFSS used canonical variate analysis (CVA) to identify stable and unstable plants under feedback control. The control laws were developed online using linear quadratic control design and the CVA identified plant. The AFSS was tested for changing wind tunnel conditions, different external store configurations, and a sudden change from a stable plant to an unstable plant by the release of an external store.
