Abstract:An aeroelastic dynamic model of a flapping wing is essential for developing effective control algorithms for roboticbirds. In this study we present a port based Hamiltonian multirigid-body approach to model the flapping wing of the Robird: a robotic bird of prey. Three models with a respectively 4, 11 and 24 bodies have been created. Some -difficult to estimatestructural and aerodynamic parameters of these models have been estimated with a genetic algorithm. Input for this genetic algorithm are (besides the models) 3D measurements of the Robird’s wing in both a vacuum chamber and wind tunnel. The result is a dynamic model of a flapping which simulates the dynamics of the wing of the Robird. It is proven that the genetic algorithm method contributes to the accuracy of the model. However, the largest errors in the model are probably due to the assumptions and simplifications. Therefore it remains unproven that the genetic algorithm is the best method to create more accurate models.
