英文摘要: Multiple autonomous underwater vehicles(multi-AUV) formation mapping plays a very important role in tridimensional monitoring ocean enviroment by employing AUVs. This program will be engaged in under-actuated multi-AUV formation mapping. In full consideration of weak communication and observation conditions, this program will systematically and intensively carry out theoretic research on multi-AUV underwater acoustic communication, mutual localization, formation and map construction. Based on Laplacian potential associated fuction, investigation will be made on consensus problems of network with switching topography, in order to establish reliable underwater acoustic communication network. In accordance with nonlinear under-actuated AUV dynamic model, adaptive controller will be developed to compensate for sea currents influence, and therefore to progress relative position measurements and mutual localization technique between AUVs. A hierarchical control architecture will be introduced to upgrade multi-AUV formation ability of intelligence and enviromental adaptivity. The top controller will deal with online formation control through multi-AUV reinforcement learning on the basis of fuzzified classifier, while the bottom cotroller will implement formation maintenance through adaptive controller.
