The emergence of synchronization in a complex network of phase oscillators is raising a considerable interest in multidisciplinary research. One application of this theory refers to systems of multiple autonomous agents, such as ground vehicles, unmanned aerial vehicles, satellites constellations, etc., who interact to each other aiming to accomplish tasks in a cooperative manner. The cooperative autonomous agents are designed here as systems of coupled oscillators, whose synchronous states may be associated to possible group and subgroup formations. In this scenario, we consider delayed interactions, which are caused by the long distances among the agents or by the limitations present in their communication channels. The aim of this project is the development of specific strategies for group control and synchronization that take into account the effects of this delayed coupling. This is part of the Doctorate Fapesp project number 2017/04552-9. To achieve this goal we rely on the expertise of the researchers of the institution to be visited, which is our partner in the thematic project 2015/50122-0.
