Distributed prescribed-time attitude cooperative control for multiple spacecraft

This paper addresses the problem of distributed prescribed-time attitude cooperative control for a group of spacecraft subject to bounded external disturbances. Since the desired attitude is only available to a subset of spacecraft, a distributed prescribed-time observer is designed to estimate the desired attitude. Based on the desired attitude observer, a distributed prescribed-time attitude cooperative controller is designed to make the attitude of each spacecraft track cooperatively the desired attitude though only a subset of spacecraft can access the desired attitude. The Lyapunov stability theorem is employed to validate that the attitude tracking is achieved in a prescribed time under the control scheme. Finally, the results of numerical simulation are presented to show the effectiveness and reliability of the proposed control scheme. (C) 2021 Elsevier Masson SAS. All rights reserved.

Automated summary

This paper addresses the problem of distributed prescribed-time attitude cooperative control for a group of spacecraft subject to bounded external disturbances. A distributed prescribed-time observer and controller are designed to achieve attitude tracking of spacecraft. Numerical simulation results validate the effectiveness and reliability of the proposed control scheme.
