System identification using in situ experimental data for the development of an hexapod surfing simulator

The global aim of the SIMUSURF project is to optimize the control of the trajectory of the moving platform of a hexapod to reproduce surfing trajectories in controlled environment. The first step of this study was to constitute a database precisely defining the different relations between the loads of the surfer and the dynamic of his surfboard. An instrumented surfboard has been built and an experimental campaign has been led. This article presents the system identification of a dynamical multivariable model about surfing trajectories using the experimental database and how to use it in the simulator.
