Given the few unsuccessful space missions in the past few decades, designing a fault-
tolerant spacecraft's attitude control has piqued the scientific and academic community's …

This paper investigates the attitude tracking problem for the flexible spacecraft composed of
a rigid platform with a rotating appendage. Two robust attitude controllers, each matched to …

An efficient and cost-effective finite-time fault-tolerant attitude controller for a class of flexible
spacecraft is designed in this paper to cater to flexible appendages' vibrations, along with …

For space optical payloads, it is difficult to achieve vibration suppression and high precision
pointing due to broadband range of micro-vibration. This paper thus presents one two-stage …

This paper builds a dual isolation system for suppressing the micro-vibration due to flywheel
of optical satellite. The advantages of this system compared to the single-layer vibration …

Abstract A Generalized Differential Quadrature (GDQ) as an accurate numerical technique
based on non-uniform grid point distribution, Chebyshev-Gauss-Lobatto (CGL) and Roots of …

Abstract Space optical clocks with frequency instability better than 1× 10− 15 are
increasingly demanded for PNT (positioning, navigation, and timing) and space physical …

The interaction between angular motion and flexible vibrations can heavily affect the stability
of the spacecraft. Many control strategies have been developed for solving this issue. Some …

Space observation missions demand stringent pointing requirements. This article thus
investigated a dual-stage vibration isolation and precision pointing system consisting of a …

This paper focuses on the leader-follower attitude consensus of multiple under-actuated
flexible spacecraft without system damping based on attitude measurements only. By …
