Nonlinear system identification tools applied to the modeling of submarine dynamics
Nonlinear system identification tools applied to the modeling of submarine dynamics
This paper presents initial work on the system identification of hydrodynamic coefficients used in fully coupled, non-linear submarine motion equations. The identification processes uses the sequential quadratic programming technique. The paper briefly describes the form of the non-linear equations use in the submarine simulation, outlines the system identification technique used and concludes by considering three identification cases. These cases are based on horizontal motion only and try to identify the coefficients assuming they are completely unknown, partially known and partially known but with an error on the known values.

Abstract
This paper presents initial work on the system identification of hydrodynamic coefficients used in fully coupled, non-linear submarine motion equations. The identification processes uses the sequential quadratic programming technique. The paper briefly describes the form of the non-linear equations use in the submarine simulation, outlines the system identification technique used and concludes by considering three identification cases. These cases are based on horizontal motion only and try to identify the coefficients assuming they are completely unknown, partially known and partially known but with an error on the known values.
