Rapid localization of autonomous underwater vehicles (AUVs) plays an important role in target pursuit tasks. We study active localization method for AUVs using noisy relative measurement
which achieves the precise position estimate of AUVs as quickly as possible under inaccurate initial estimates. A framework for active localization of AUVs with excellent scalability is proposed
which is composed of measurement module
control module and estimation module. In control module we design the motion strategy for AUV
which makes simultaneous convergence of position estimate and the relative geometric location between AUV and beacon. Using noisy relative measurement
a method based on reinforcement learning is adopted to achieve the motion strategy. The numerical simulation results show that the proposed framework and motion strategy has better rapidity and robustness than the traditional localization method.
