Predefined‐Time Hierarchical Scheme for Time‐Varying Formation Tracking of Hybrid Networked Marine Systems

International Journal of Robust and Nonlinear Control
ABSTRACTThis paper addresses the time‐varying formation tracking (TVFT) problem for surface‐underwater hybrid networked marine systems (HNMSs) amid parametric uncertainties, external disturbances, as well as unmodeled hydrodynamics. The system includes multiple autonomous surface vehicles (ASVs) and autonomous underwater vehicles (AUVs). To tackle this

Resilient Time-Varying Formation-Tracking of Multiagent Systems Against Hybrid Attacks With Applications to Spacecraft Formation

IEEE Transactions on Cybernetics
This work investigates the time-varying formation-tracking problem of multiagent systems under hybrid attacks, including denial-of-service (DoS) attacks and actuation attacks. State estimators are designed for each node of the swarm leveraging relative information from neighboring estimators to generate the desired positional states for formation ...

Robust Trajectory Tracking in Satellite Time-Varying Formation Flying

IEEE Transactions on Cybernetics, 2021
The robust time-varying formation control problem for a group of satellites is addressed. By the static state feedback control strategy and the disturbance estimation theory, a formation flying controller is proposed for the satellite group to form desired time-varying formation patterns and trajectories, and achieve the satellite attitude consensus ...

Bearing-Based Formation Tracking Control With Time-Varying Velocity Estimation

IEEE Transactions on Cybernetics, 2023
This article studies the bearing-based formation tracking control problem of multiple double-integrator agents. A leader-following structure, where the leader moves with the reference dynamics, is adopted. Different from the existing methods, which require complete information of the time-varying reference velocity, in this article, only the time ...
