Automatic simulation programs of ship navigation can be a powerful tool for operational planning and design studies of waterways. In such a simulation system the key tasks of autonomous route-finding and collision-avoidance are performed by the simulation program itself with no or minimum intervention...
Automatic simulation of ship manoeuvring has to be able to con the ship automatically to reach a destination point whilst avoiding other ships and navigational hazards, keeping well clear of non-navigable areas, such as shallow water and shore line. One of the key problems in this task is ...
Track-keepers are being designed containing novel features which enable a ship's response to be adjusted to the known requirements of a port area. In addition to describing the track-keeper, their use as a design tool in simulation studies for identifying critical manoeuvring areas and determining...
Over the past seventy years many advances have been made in the field of ship control. Early developments on proportional controllers have led to today's modern control systems which have interfacing capabilities with electronic navigation equipment. This research investigates traditional control ...
Aiming at the problems of sparse features, polysemy of one word and less context related information in short text automatic scoring, a short text automatic scoring model based on bidirectional encoder representations from transformers - bidirectional long short-term memory (BERT-BiLSTM) is proposed....
The research of propulsion system matching calculation of hybrid diesel and wind propulsion ship By comprehensive comparison of different navigation mode-fixed navigation speed and fixed load, this paper determines fixed navigation speed as the navigat...

which makes the calculation simple and easy to implement in engineering. On this basis, the reverse step control law is designed. Thirdly, the stability of the system is proved based on Lyapunov stability theory. Finally, the simulation results show that the control law can make the ship reach...
we look into the navigation and guidance system and the flight control methods for current different aircraft.Finally,we draw several conclusions of the development prospects for aircraft carrier landing,including the precision landing control techniques,precision approach and landing guidance techniques,and...
The design project and realization approach to simulate ship and rudder control system of course, track autopilot in real navigation environment are introduced which combine digital simulation with physical simulation. 给出了采用数字模拟与物理模拟相结合的方法模拟海上实船环境的航向、航迹自动操舵仪船—舵...
Automatic navigation in complicated environment is one of the necessary capabilities for USVs. As a sophisticated task, it is vital to ensure that the ship sails from the fairway area to the designated berthage with a proper speed and meets the heading requirements when a ship enters a port ...
