Sensitivity of computer support game algorithms of safe ship control

Abstract

The paper investigates the sensitivity of safe ship control to inaccurate data from the ARPA anti-collision radar system and to changes in the process control parameters. The system structure of safe ship control in collision situations and computer support programmes exploring information from the ARPA anti-collision radar are presented. Sensitivity characteristics of the multistage positional non-cooperative and cooperative game and kinematics optimization control algorithms are determined through examples of navigational situations with restricted visibility at sea.

Comparison of Fuzzy System with Neural Aggregation FSNA with Classical TSK Fuzzy System in Anti-Collision Problem of USV

“…USVs moving in a marine environment are exposed to collisions with stationary obstacles as well as moving obstacles, mainly other vessels occurring in USV's operation area. Therefore, a significant problem appearing in the USV motion is counteracting possible collisions [5,7,20]. Software responsible for the anti-collision usually cooperates with navigation devices such as: a radar system, an AIS receiver, GPS, a speed log, a gyrocompass, etc., and actuators such as: a propeller, a rudder, and additionally cooperates with software for route planning [14] and an electronic navigation map [9].…”

Multi-Objective Weather Routing of Sailing Vessels

“…Only a few articles since the '60s to nowadays [9,15,3,13] present the development of research on the route planning of sailing vessels. Discretization of vessel's motion can be found in [23,24,11]. Advanced deterministic route planning algorithms are presented among others in [2,6,17].…”

“…The predicted heel value is dependent on the specific wind vector and the chosen move direction from P k to P k+1 (11): (11) where: α k,k+1 -Course Over Ground from P k to P k+1 , β k,k+1 -relative wind direction,…”

Heuristic Method of Safe Manoeuvre Selection Based on Collision Threat Parameters Areas

“…These solutions, among others, include various methods and tools dedicated to collision avoidance. They range from optimal ship control (Lisowski 2013, Lisowski 2014) through ship trajectory planning (Lazarowska 2015, Lazarowska 2016 to determining and visualizing safe manoeuvres, which is addressed in the hereby paper.…”
