| 英文摘要 |
| This paper discusses the oil spill plume monitoring by multiple unmanned surface vehicles (USVs), where the
plume propagation is modeled by an advection-diffusion process in two-dimensional space. The main objective of this paper
is to construct a leader-follower-anchor-based cooperative control law for USVs such that all vehicles track the expansion of
the plume front described by a level set with a pre-specified threshold value and simultaneously forms an even distribution
on this plume front. To this end, two vehicles are assigned as boundary leader and anchor one, respectively, and the other
ones are assigned as followers. By local averaged concentration measurements from the chemical sensors equipped on
USVs, a distributed-consensus-observer-based cooperative control law is developed to achieve the main objective of this
paper. The convergence of the suggested cooperative guidance laws is analyzed rigorously by the Lyapunov technique, set
stability, and multi-agent cooperative control theory. Finally, numerical simulations are provided to support the suggested
cooperative control laws. |
