Abstract
ZONA Technology, Inc. (ZONA) proposes to develop an on-line flutter prediction tool for wind tunnel model using the parameter varying estimation (PVE) technique to ensure the safety of the flutter model as well as the wind tunnel system. This tool will be applied to rapidly evaluate parameters, such as modal damping and frequency, which are required to assess the flutter boundary of a wind tunnel model in the pre-flutter test conditions. In this PVE Toolbox, system identification techniques such as Polymax and Subspace methods are employed to consistently estimate the damping/frequency of the physical modes, followed by the implementation of Zimmerman-Weissenburger flutter margin method, linear parameter varying modeling combined with
