In this paper, we propose a new quaternion-based feedback control scheme for exponential
attitude stabilization of a four-rotor vertical takeoff and landing aerial robot known as a …

This paper deals with the design and implementation of a nonlinear control algorithm for the
attitude tracking of a four-rotor helicopter known as quadrotor. This algorithm is based on the …

In this paper, we propose a quaternion-based feedback control scheme for exponential
attitude stabilization of a four-rotor vertical take-off and landing (VTOL) aerial robot known as …

The problem of inertial pointing for a spacecraft with magnetic actuators is addressed and an
almost global solution to the problem is obtained by means of static attitude and rate …

A position and attitude tracking control law for autonomous underwater vehicles (AUV's) in 6
degrees of freedom (DOF) is derived. The 4-parameter unit quaternion (Euler parameters) is …

The problem of H/sub/spl infin//control of a rigid spacecraft with three control torques and
disturbances is addressed. The Hamilton-Jacobi-Isaacs inequality for H/sub/spl …

This paper deals with the design and implementation of the super twisting control algorithm
for the attitude tracking of a four rotors helicopter known as quadrotor. The choice of this …

A magnetocoulombic satellite system is proposed and equations are developed to study the
stability and control characteristics for a set of given initial conditions. An equation for charge …

This paper is concerned with magnetic attitude control of spacecraft. The operation of the
magnetic actuators is usually on a duty cycle; during the off times in this duty cycle the …

Commercially viable aerial robotic vehicles require robust and efficient, but low-cost attitude
(vehicle orientation) stabilisation systems. A typical attitude stabilisation system employs a …
