Robust Satellite Formation Flying Controller Design Subject to Communication Delays

IEEE Access, 2020
A robust control method is proposed to address the satellite formation flying problem subject to communication delays. Each satellite dynamics involves nonlinear dynamics, parametric uncertainties, and external disturbances.

Consensus and coordination on groups SO(3) and S3 over constant and state-dependent communication graphs

Automatika, 2021
We address several problems of coordination and consensus on $ SO(3) $ and $ S^3 $ that can be formulated as minimization problems on these Lie groups.
