Abstract

In this paper the mathematical model of the closed loop system: submarine, steering gear and controller is defined. A preliminary stability analysis has been performed. Several different control algorithms are investigated for the "real world" conditions and for various environmental regimes. A nonlinear model of steering gear for overcoming a "derivative" kick was included. Simulink has been used to test the controller performance and results are given. A disturbance model is proposed and its effect on the control system is outlined.
