In this article, a neural-network-based adaptive fixed-time control scheme is proposed for the
attitude tracking of uncertain rigid spacecrafts. A novel singularity-free fixed-time switching …

Developing the essential theory for architecting and tackling issues faced during complex
realistic engineering problems, this volume focuses on enhanced anti-disturbance control …

In this paper, we systematically introduce a novel geostationary orbit (GEO) space debris
removal system called dexterous tethered space robot (DTSR). The DTSR has three notable …

This paper presents a new approach to vibration reduction of flexible spacecraft during
attitude maneuver by using the theory of variable structure control (VSC) to design switching …

In this paper, the attitude maneuver control without unwinding for rigid spacecraft is
addressed based on the modified Rodrigues parameters (MRPs). First of all, an attitude …

In this article, a predefined-time approximation-free attitude constraint control scheme is
proposed for rigid spacecraft with external disturbances. By combining the backstepping …

Target capturing is an essential and key mission for tethered space robot (TSR) in future on-
orbit servicing, and it is quite meaningful to investigate the stabilization method for TSR …

TETHERED space robot (TSR) systems consist of a gripper, a space tether, and a space
platform (Fig. 1) for future use in onorbit services including on-orbit maintenance, on-orbit …

The authors propose a simple and effective fault tolerant control method for satellites with
four reaction wheels. The proposed method is based on dynamic inversion and time-delay …

When the spacecraft reaches the end of life, its payload will still be able to work in most
cases. Due to the loss of attitude control ability, these failed satellites had to be abandoned …
