Predictor-Based LOS Guidance Law for Path Following of Underactuated Marine Surface Vehicles with Sideslip Compensation

This paper presents a novel predictor-based line-of-sight (PLOS) guidance law for the path following of underactuated marine surface vehicles. A predictor is developed for the estimation of vehicle sideslip due to environmental disturbances. The proposed guidance law not only preserves the simplicity and interpretation of classical line-of-sight (LOS) guidance, but also enables smooth and fast identification of the vehicle sideslip angle. By using a cascade stability theory, the equilibrium point of the close-loop system is shown to be uniform global asymptotic stable. The transient property is quantified by deriving the L2 norm of the derivative of the adaptive signal, which can be reduced by choosing design parameters. Both simulation and experimental results are provided to validate the effectiveness of the method.
