Attitude Control of Spacecraft Formations Subject To Distributed Communication Delays
Provides a theoretical framework for ensuring attitude consensus in spacecraft formations under realistic communication delays, but is incremental as it applies known control methods to a specific domain.
The paper addresses attitude consensus in spacecraft formations with bounded, time-varying communication delays, proposing a state feedback controller and deriving delay-dependent stability criteria via LMIs and the small-gain theorem, validated by simulations.
This paper considers the problem of achieving attitude consensus in spacecraft formations with bounded, time-varying communication delays between spacecraft connected as specified by a strongly connected topology. A state feedback con- troller is proposed and investigated using a time domain approach (via LMIs) and a frequency domain approach (via the small-gain theorem) to obtain delay depen- dent stability criteria to achieve the desired consensus. Simulations are presented to demonstrate the application of the strategy in a specific scenario.
