Some weak flocking models and its application to target tracking

[摘要] In this paper, we introduce a new concept named the weak flocking behavior. That is, if the complex system has the weak flocking property, the agents do not need have the same velocities to keep together when t -> infinity. This shows the biggest difference between weak flocking behavior and the flocking behavior. The advantage of this concept is that its practical significance-the agents don't need always keep in step in lots of the complex systems but they still keep together. Then, we propose a weak flocking model with two agents and study two different mechanisms for this model. Moreover, we also consider a system with N agents. Under the weak link mechanism, the system with N agents can keep weak flocking. (C) 2019 Elsevier Inc. All rights reserved.
