Path following of underactuated marine surface vessels using line-of-sight based model predictive control
This paper presents a model predictive control (MPC) for a way-point tracking of underactuated surface vessels with input constraints. A three-degree-of-freedom dynamic model of surface vessels has been used for the controller design. In order for the control action to render good helmsman behavior, a MPC scheme with line-of-sight (LOS) path generation capability is formulated. Quadratic progra...
متن کاملA planar path following controller for underactuated marine vehicles
Inspired by the previous work of Aicardi et al.[1] a path following controller for underactuated planar vehicles is designed by adopting a polar-like kinematic model of the system. The solution proposed does not generally guarantee null asymptotic path following error, but only its boundedness below an adjustable upper threshold. However, knowledge of the path curvature is not necessary, thus r...
متن کاملLine-of-sight Path following of Underactuated Marine Craft
A 3 degrees of freedom (surge, sway, and yaw) nonlinear controller for path following of marine craft using only two controls is derived using nonlinear control theory. Path following is achieved by a geometric assignment based on a line-of-sight projection algorithm for minimization of the cross-track error to the path. The desired speed along the path can be specified independently. The contr...
متن کاملObserver Based Path Following for Underactuated Marine Vessels in the Presence of Ocean Currents: A Local Approach - With proofs
In this article a solution to the problem of following a curved path in the presence of a constant unknown ocean current disturbance is presented. The path is parametrised by a path variable that is used to propagate a path-tangential reference frame. The update law for the path variable is chosen such that the motion of the path-tangential frame ensures that the vessel remains on the normal of...
متن کاملStraight Line Path Following for Formations of Underactuated Surface Vessels under Influence of Ocean Currents
The problem of path following and formation control for underactuated 3-degrees-of-freedom surface vessels in the presence of unknown ocean currents is considered. The proposed controllers make the vessels asymptotically constitute a desired formation that follows a given straight-line path with a desired speed profile. This control goal is achieved in the presence of currents of unknown direct...
