摘要
A dynamically positioned ship maintains its position (fixed location or predetermined track) exclusively by means of active thrusters. In this paper, a control scheme for dynamic positioning control of ships using a relay observer design is presented. Our analysis relies on nonsmooth strict Lyapunov functions to demonstrate global asymptotic stability of the closed-loop system equilibrium. Using simulation results we illustrate the good performance of the proposed scheme under noisy ship position measurements.
