The LPV models of ship steering and main engine speed were established depending on ship speed etc as the scheduling parameters.

For Norrbin ship mathematical model with nonlinear and uncertain characteristics,the ship steering robust controller was designed successfully based on backstepping algorithm and nonlinear damping algorithm.

A new approach to design a systematic switching linear parameter-varying controller to determine if it is practical to use for ship steering was presented,which aimed at nonlinear of ship steering.

Design of an intelligent self-adaptive control system for ship course based on IGA-BP algorithms;

H~∞ robust control for ship course

Based on the dynamic surface control method,a design scheme is proposed for ship course control system with parametric uncertainties and modeling uncertainties, as well as unknown bounded exogenous disturbances.
