This paper considers a trajectory-tracking control algorithm for underactuated marine vehicles moving horizontally in which the current North-East-Down frame is constant. modification of scheme based on input-output feedback linearization method application condition that vehicle symmetric with respect to left and right sides. The proposed can be applied fully asymmetric model, and, therefore, ...

Energy efficiency and safety are two critical objectives for marine vehicles operating in environments with obstacles, they generally conflict each other. This paper proposes a novel online motion planning method vehicles, which can take practical limitations into account make trade-offs between the by exploiting economic model predictive control (EMPC) technique. To achieve this, trajectory ge...

In recent years, with the development and progress of science technology, all kinds water underwater vehicles have been gradually integrated into commercial civil marine operations, which are self-energy, autonomous control, flexible convenient, can be widely used in fish monitoring, population migration, environmental protection, early warning, survey, etc., while better attitude adjustment po...

Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity.[1] The earliest studies of marine biology can be traced back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition.[2] However, it was Aristotle (384-322 BC) who was the first to record any observatio...

Spawned by recent advances in technology, widespread attention has been focused on the coordination of multiple autonomous vehicles. In numerous mission scenarios, the concept of a group of agents cooperating to achieve a determined goal is very attractive when compared with the solution of one single, heavily equipped vehicle, as it exhibits better performance in terms of efficiency, flexibili...
