Abstract:

The capability of applying a sequential estimation technique of system identification to determine unknown coefficient values in the vertical plane equations of motion for a hydrofoil craft is investigated where the craft has random forcing functions andor measurement noise contamination. Results are obtained from experiments using trajectory data supplied from computer simulation with known coefficient values as well as from full scale measurements. The utility of the method and the construction of mathematical models is described. Author
