A new approach to control, stabilization and disturbance rejection of attitude subsystem of
quadrotor is presented in this article. Analytical method is used to tune conventional …

The aim of this paper is to design a globally robust and globally finite-time convergent
attitude controller for a rigid spacecraft. Second order sliding mode control in integral sliding …

This paper presents an anti‐unwinding control method for the attitude stabilization of a rigid
spacecraft. Quaternion has double stable equilibrium and this may cause unwinding …

The time-optimal control problem of a hovering quad-rotor helicopter is addressed in this
paper. Instead of utilizing the Pontryagin's Minimum Principle (PMP), in which one needs to …

In this paper the three axes slewing maneuver and the vibration suppression of a flexible
spacecraft are studied. The satellite has a central rigid body and two flexible appendages …

This article introduces a time-optimal reorientation manoeuvre controller with saturation
constraints on both reaction wheels' torques and angular momentum. The proposed control …

This paper investigates the time efficient maneuver of rigid satellites with inertia uncertainty
and bounded external disturbance. A redundant cluster of four reaction wheels is used to …

In this paper, a robust adaptive finite time sliding mode control method is proposed for the
attitude control of a rigid spacecraft. The proposed control method is derived using a novel …

The paper deals with the problem of time-optimal spacecraft reorientation maneuvers by
means of reaction wheels, with boundary and path constraints. When searching for solutions …

A finite-time continuous sliding mode control is proposed and designed for the attitude
control of an earth-pointing magneto-Coulombic satellite actuated using Coulomb shells and …
