Surface Vessel Tracking in Airborne Infrared Imagery [PDF]
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019 Visual target tracking has been studied for decades and still remains a challenging problem. Ship tracking on infrared images has numerous challenges compared to conventional target tracking such as fast changing of appearance. Rapid appearance change caused by the manoeuvring movement of the target of image acquiring platform, confusion and occlusion ...

Multi-under-Actuated Unmanned Surface Vessel Coordinated Path Tracking
Sensors, 2020 Multi-under-actuated unmanned surface vehicles (USV) path tracking control is studied and decoupled by virtue of decentralized control. First, an improved integral line-of-sight guidance strategy is put forward and combined with feedback control to ...

Application of a New Shore-Based Vessel Traffic Monitoring System Within San Francisco Bay
Frontiers in Marine Science, 2020 Vessel traffic management systems can be employed for environmental management where vessel activity may be of concern. One such location is in San Francisco Bay where a variety of vessel types transit a highly developed urban estuary. We analyzed vessel

Adaptive output tracking control of a surface vessel [PDF]
2008 47th IEEE Conference on Decision and Control, 2008 In this paper, the tracking control of a three degree-of-freedom marine vessel is examined. The novelty of this work is the transformation of the asymmetric inertia matrix into a symmetric, positive definite matrix. The asymmetry arises from the added mass common to practical surface vessels and creates a significant challenge for control design.

Nonlinear tracking control of underactuated surface vessel [PDF]
Proceedings of the 2005, American Control Conference, 2005., 2005 We consider in this paper the tracking control problem of an underactuated surface vessel. Based on the cascaded structure of tracking error dynamics, we present two new tracking controllers using Barbalat's lemma and back-stepping techniques under mild assumptions on the reference trajectory.

Robust MPC-Based Fault-Tolerant Control for Trajectory Tracking of Surface Vessel
IEEE Access, 2018 A robust control method, based on a model predictive control, is developed for the trajectory tracking of a surface vessel with sensor failures. The kinematic model of a surface vessel is first obtained.
