Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In order to enhance the development of marine resources, this study investigates the problem of discrete-time multi-autonomous underwater vehicles (AUV) formation coordination control with leader-following consensus under time-varying delays. First, a discrete-time second-order integration model for AUVs is presented. Second, considering the existence of time-varying delays in AUV communication, the communication between multiple AUVs is classified as valid or invalid based on the maximum delay limit. The problem of AUV formation control under invalid communication is transformed into a formation control problem under switching communication topologies. Then, a time-varying delay communication synchronization strategy is designed to convert asynchronous state information into synchronous state information. Based on synchronous state information, a leader-following consensus control protocol with time-varying delays is proposed, and a controllability analysis is conducted using Lyapunov–Krasovskii functionals. Finally, the stability and effectiveness of the proposed formation-coordination controller and delay synchronization strategy were validated through simulation experiments.
