title = "Adaptive modal identification for flutter suppression control",
abstract = "In this paper, we will develop an adaptive modal identification method for identify- ing the frequencies and damping of a utter mode based on model-reference adaptive control (MRAC) and least-squares methods. The least-squares parameter estimation will achieve parameter convergence in the presence of persistent excitation whereas the MRAC parameter estimation does not guarantee parameter convergence. Two adaptive utter suppression control approaches are developed: one based on MRAC and the other based on the least-squares method. The MRAC utter suppression control is designed as an integral part of the parameter estimation where the feedback signal is used to estimate the modal information. On the other hand, the separation principle of control and estimation is applied to the least-squares method. The least-squares modal identification is used to perform parameter estimation.",
