The estimation of the heave, pitch, roll, sway, and yaw motions of a DD-963 destroyer is studied, using Kalman filtering
techniques, for application in VTOL aircraft landing.
The governing equations are obtained from hydrodynamic considerations in the form of Linear differential equations with frequency
dependent coefficients. In addition, nonminimum phase characteristics
are obtained due to the spatial integration of the water wave forces.
The resulting transfer matrix function is irrational and nonminimum phase. The conditions for a finite-dimensional approximation are considered and the impact of the various parameters is assessed.
A detailed numerical application for a DD-963 destroyer is presented and simulations of the estimations obtained from Kalman filters are discussed.
