Attitude control of satellites with delay in attitude measurement

2013 IEEE International Conference on Robotics and Automation, 2013
Time delay in attitude sensors is one of the performance limiting factors in controlling the satellite attitude. In this paper, we investigate attitude control of a fully actuated satellite in presence of constant and known delay in attitude measurement.

ADAPTIVE CONTROL OF MISSILE ATTITUDE

IFAC Proceedings Volumes, 1987
Abstract The attitude control of a missile should not only be able to make it follow predetermined Euler angles but also minimize the effects of wind gusts along its trajectory. Fixed gain controllers with good performance are impaired by the highly nonstationary nature of the missile dynamics.

Skylab Attitude Control System

IBM Journal of Research and Development, 1976
The attitude stabilization and control system for Skylab evolved from an analog controller into a fully digital processing system. Features of this system include a software-determined attitude reference to provide general maneuvering ability, an in-orbit programming capability, the use of large control moment gyros for attitude control, and the use of

Attitude control of a spinning Skylab

Guidance and Control Conference, 1972
Active attitude control of a spinning Skylab is analyzed to determine a simple control law that will provide a satisfactory response, considering the dynamics of attached flexible appendages. A simplified model of the complex Skylab vehicle is selected to make it analytically tractable.

Attitude estimation and control of a quadrocopter

2010 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2010
The research interest in unmanned aerial vehicles (UAV) has grown rapidly over the past decade. UAV applications range from purely scientific over civil to military. Technical advances in sensor and signal processing technologies enable the design of light weight and economic airborne platforms. This paper presents a complete mechatronic design process

Attitude Control of a Flexible Spacecraft

Journal of Guidance and Control, 1980
An algorithm is presented for designing optimal low order compensators for high order systems and it is applied to the title problem where many vibration modes are excited by the control torque. These low order compensators are compared with the full order optimal compensator and found to be less sensitive to modeling errors and to provide near optimal

Distributed attitude synchronization control

IEEE Conference on Decision and Control and European Control Conference, 2011
In this paper we consider the problem of constructing feedback control laws for a system of n agents that shall synchronize their attitudes in SO(3). We propose distributed controllers for two synchronization problems, in which the objective is the same, to synchronize the orientations, but what the agents can perceive or communicate differs.

Robust attitude control for spacecraft

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
The paper deals with the spacecraft attitude tracking problems in the presence of model uncertainties and external disturbances. A modified VSC design scheme is proposed by the use of variable structure control (VSC) design technique. These modified VSC laws are continuous, which are shown able to alleviate the chattering drawback inherited from sign ...

Rigid Body Attitude Control With Delayed Attitude Measurement

IEEE Transactions on Control Systems Technology, 2015
Time delay in the evaluation of the attitude of a rigid body can significantly hinder the performance of the attitude control system. In this brief, we propose a dynamically smooth control law that guarantees asymptotic convergence of the rigid body attitude and angular velocity to their desired values in the presence of delayed attitude measurement ...
