DOI: 10.1016/j.actaastro.2021.02.019
Abstract: Abstract Future Active Debris Removal missions will require an autonomous spacecraft (chaser) to safely monitor at close distance, and then approach and dispose an inactive artificial space object (target). Since these targets are uncooperative, meaning… read more here.

DOI: 10.1109/jsac.2023.3242708
Abstract: Distributed estimation of 6-DOF relative states, including three-dimensional relative poses and three-dimensional relative positions, is a key problem in UAV (Unmanned Aerial Vehicle) networks, which generally requires vision-involved iterative state estimation. How to achieve communication… read more here.

DOI: 10.1109/tcns.2015.2506905
Abstract: We study asymptotic dynamical patterns that emerge among a set of nodes interacting in a dynamically evolving signed random network, where positive links carry out standard consensus, and negative links induce relative-state flipping. A sequence… read more here.

DOI: 10.1109/tcyb.2019.2954955
Abstract: The relative state between neighbors represents the difference of two connected agents’ states, and it possesses specific physical meanings in practice. Under this background, the saturation constraints in the relative state inevitably occur. This article… read more here.

DOI: 10.1109/tits.2022.3174060
Abstract: In this article, we study the distributed control problem of vehicular platooning by taking into account network imperfections, namely the input delay and the packet dropout. The delay occurs within the inter network of each… read more here.
