The application provides a multi-AUV system formation coordination control method with non-convex control input constraints, converts the coordination control of the multi-AUV system formation without a leader into a formation consistency problem, and defines the consistency state of the multi-AUV system formation without a leader. In the case that the water acoustic communication bandwidth is limited, the application selects a double-layer communication channel mainly composed of position and speed information.

By using the properties of graph theory, random matrix and SIA matrix, and selecting appropriate controller parameters, the multi-AUV system formation can reach the defined consistency state and maintain the stability of the formation shape.

A system can automatically search and gather participant information in connection with an event. The search for participant information for a participant is triggered when a positive action for the event is received from the participant. The participant information is gathered from at least one of public, private and software platform resources. The gathered participant information is processed to resolve consistency issues due to the different sources. The resolved participant information is formatted and transmitted to the client devices for display and stored in private resources associated with the participant.
