Global Robust Adaptive Trajectory Tracking Control for Surface Ships Under Input Saturation

IEEE Journal of Oceanic Engineering, 2020
In this paper, we investigate the trajectory tracking control problem of surface ships subject to unknown parameters, unknown time-varying disturbances, and input saturation. The input saturation is approximated using a Gaussian error function.

Finite-Time Formation Control of Under-Actuated Ships Using Nonlinear Sliding Mode Control

IEEE Transactions on Cybernetics, 2018
A novel nonlinear sliding mode control approach dealing with the formation control of under-actuated ships is presented in this paper. To avoid the singularity problem, state space of the system is partitioned into two regions, with one region bounded ...
