Available in PDF, EPUB and Kindle. Book excerpt: A general procedure for the design and analysis of three-axis, large-angle attitude control systems has been developed. Properties of three-dimensional rotations are used to formulate a model of such systems. The model is general in that it is based on those properties which are common to all attitude control systems, rather than on special properties of particular components. Numerical values are assigned to attitude error by means of error functions. These functions are used to construct asymptotically stable control laws. The overall (global) behavior of the system is characterized by the envelope of all time histories of attitude error generated by every possible combination of initial condition, target attitude motion, and disturbance. A method for computing upper bounds on the response envelope is presented. Applications of this method indicate that it provides a useful alternative to Liapunov analysis for the determination of system stability, responsiveness, and sensitivity to disturbances, parameter variations, and target attitude motion.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to serve both as a practical technical reference and a resource for gaining a fuller understanding of the state of the art of spacecraft momentum control systems, specifically looking at control moment gyroscopes (CMGs). As a result, the subject matter includes theory, technology, and systems engineering. The authors combine material on system-level architecture of spacecraft that feature momentum-control systems with material about the momentum-control hardware and software. This also encompasses material on the theoretical and algorithmic approaches to the control of space vehicles with CMGs. In essence, CMGs are the attitude-control actuators that make contemporary highly agile spacecraft possible. The rise of commercial Earth imaging, the advances in privately built spacecraft (including small satellites), and the growing popularity of the subject matter in academic circles over the past decade argues that now is the time for an in-depth treatment of the topic. CMGs are augmented by reaction wheels and related algorithms for steering all such actuators, which together comprise the field of spacecraft momentum control systems. The material is presented at a level suitable for practicing engineers and those with an undergraduate degree in mechanical, electrical, and/or aerospace engineering.
Download or read book Attitude Control of a Spacecraft with a Strapdown Inertial Reference System and Onboard Computer written by John Hrastar and published by . This book was released on 1970 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A strapdown inertial reference system and an onboard digital computer can be used to change the attitude of a spacecraft over large angles in an arbitrary direction. A study was conducted with an advanced Orbiting Astronomical Observatory (OAO) using a three-axis control law previously proven globally stable. The control system can reorient the spacecraft to an arbitrary inertial attitude with a single command by operating the three momentum wheels simultaneously. Reorientation, therefore, becomes a simple extension of a hold or pointing mode. The time required for reorientation with this system is considerably shorter than the time required for a series of single-axis slews. The spacecraft attitude and control law are continuously updated by the onboard computer's using information provided by the strapdown inertial reference system. The use of a computer and inertial reference system with characteristics of systems presently under development demonstrates the feasibility of orientation with such a reference system. The basic system is not limited to the OAO but may be adapted for other three-axis-stabilized spacecraft.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this textbook is to provide the mathematical models and algorithms needed to develop a thorough understanding of all control system functions of a rigid body spacecraft. Relatively simple, but practically applicable algorithms are presented rather than recent advances. We try to avoid detailed and specialized issues that are of less importance for the fundamental understanding, such as detailed environment models, etc. Furthermore, control problems that can be cast in standard formulations and solved with existing methods are not treated here. Instead, we intend to provide an understanding of the principles, put them in an engineering context, and try to give all explanations as concise as possible. Besides conventional three-axis attitude control systems, the following topics are treated in this book:• Control of agile rotation maneuvers using control moment gyros • Precise pointing control with error classes for pointing instruments • Control systems with accelerometers and free-flying test masses, which provide low-disturbance or disturbance-free environments We believe that these topics are of considerable relevance for the design of future spacecraft control systems, especially in the field of science and Earth observation missions.

Download or read book Commercial Satellite Launch Vehicle Attitude Control Systems Design and Analysis H infinity Loop Shaping and Coprime Approach written by Chong Hun Kim and published by Lulu.com. This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for aerospace engineers who have completed their BS degree and are interested in the design and analysis of rocket attitude control systems. It introduces a new approach to the design, characterized by its robustness. Current LV attitude control systems are designed based on classical SISO control theory, and they lack robustness. The theory used here truly offers a technique that enables us to design control systems that are reasonably insensitive to math modeling errors and can withstand disturbances such as gust, and in addition it doesn’t need external states estimator, such as Kalman filtering. Extensive simulation results, which demonstrate the effectiveness of this approach, are presented in this book. Basic rocket theory and a concept of H-infinity control system design technique are explained for those who are new in these fields of study.
