چکیده

The paper considers the dynamic positioning problem for a ship having only two independent controls, namely surge force and yaw moment. A time-varying feedback control law including integral action is developed and proved to exponentially stabilize both the North and East positions and the orientation of the ship. Experimental results are presented where the controller is implemented on a model ship, scale 1:70, of an offshore supply vessel. The experiments show that the ship converge to a neighborhood of the desired position and orientation, oscillating about stationary errors, and that with integral action in the control law these stationary errors are reduced.

Tracking control of an underactuated ship

In this paper, we address the tracking problem for an underactuated ship using two controls, namely surge force and yaw moment. A simple state-feedback control law is developed and proved to render the tracking error dynamics globally -exponentially stable. Experimental results are presented where the controller is implemented on a scale model of an offshore supply vessel.

Dynamic positioning and way-point tracking of underactuated AUVs in the presence of ocean currents

This paper addresses the problem of dynamic positioning and way-point tracking of underactuated autonomous underwater vehicles (AUVs) in the presence of constant unknown ocean currents and parametric modeling uncertainty. A nonlinear adaptive controller is proposed that steers an AUV along a sequence of way-points consisting of desired positions (x, y) in a inertial reference frame, followed by...

Dynamic Positioning of an Underactuated Auv in the Presence of a Constant Unknown Ocean Current Disturbance

This paper addresses the problem of dynamic positioning of an underactuated autonomous underwater vehicle (AUV) in the horizontal plane. A nonlinear adaptive controller is proposed that yields convergence of the trajectories of the closed loop system to a desired target point in the presence of a constant unknown ocean current disturbance and parametric model uncertainty. The controller is firs...
