This book was released on 1970 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Attitude control to ensure stability of a spacecraft sluing through large angles was experimentally investigated. The investigation examined a control law synthesized from Euler's theorem on rotation, which states that any attitude change of a rigid body may be accomplished by a single rotation about the appropriate axis. A theoretical analysis showed that a system using the control law is globally stable. The investigation was performed using an air-bearing table to simulate the spacecraft, two gimbaled star trackers as position sensors, rate gyroscopes to provide damping information, and reaction wheels as control torquers. Also a digital computer was used as a real-time controller to determine the desired axis of rotation from the star-tracker gimbal outputs and to generate simultaneous commands to all torquers so that the table would rotate about the desired axis."--P. [i].

Download or read book Spacecraft Modeling Attitude Determination and Control written by Yaguang Yang and published by CRC Press. This book was released on 2019-02-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses all spacecraft attitude control-related topics: spacecraft (including attitude measurements, actuator, and disturbance torques), modeling, spacecraft attitude determination and estimation, and spacecraft attitude controls. Unlike other books addressing these topics, this book focuses on quaternion-based methods because of its many merits. The book lays a brief, but necessary background on rotation sequence representations and frequently used reference frames that form the foundation of spacecraft attitude description. It then discusses the fundamentals of attitude determination using vector measurements, various efficient (including very recently developed) attitude determination algorithms, and the instruments and methods of popular vector measurements. With available attitude measurements, attitude control designs for inertial point and nadir pointing are presented in terms of required torques which are independent of actuators in use. Given the required control torques, some actuators are not able to generate the accurate control torques, therefore, spacecraft attitude control design methods with achievable torques for these actuators (for example, magnetic torque bars and control moment gyros) are provided. Some rigorous controllability results are provided. The book also includes attitude control in some special maneuvers, such as orbital-raising, docking and rendezvous, that are normally not discussed in similar books. Almost all design methods are based on state-spaced modern control approaches, such as linear quadratic optimal control, robust pole assignment control, model predictive control, and gain scheduling control. Applications of these methods to spacecraft attitude control problems are provided. Appendices are provided for readers who are not familiar with these topics.

Book excerpt: Spacecraft Attitude Control: A Linear Matrix Inequality Approach solves problemsfor spacecraft attitude control systems using convex optimization and, specifi cally,through a linear matrix inequality (LMI) approach. High-precision pointing and improvedrobustness in the face of external disturbances and other uncertainties are requirementsfor the current generation of spacecraft. This book presents an LMI approach to spacecraftattitude control and shows that all uncertainties in the maneuvering process can besolved numerically. It explains how a model-like state space can be developed through amathematical presentation of attitude control systems, allowing the controller in question tobe applied universally. The authors describe a wide variety of novel and robust controllers,applicable both to spacecraft attitude control and easily extendable to second-ordersystems. Spacecraft Attitude Control provides its readers with an accessible introductionto spacecraft attitude control and robust systems, giving an extensive survey of currentresearch and helping researchers improve robust control performance. - Considers the control requirements of modern spacecraft - Presents rigid and flexible spacecraft control systems with inherent uncertainties mathematically, leading to a model-like state space - Develops a variety of novel and robust controllers directly applicable to spacecraft control as well as extendable to other second-order systems - Includes a systematic survey of recent research in spacecraft attitude control
Download or read book Equilibrium Analysis and Its Application to Attitude Control Systems written by William N. Redisch and published by . This book was released on 1967 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: No theoretical technique exists yet that enables the engineer to completely determine the stability of practical complex spacecraft attitude control systems. In this dissertation, a stability approach is developed that utilizes a computer simulation in conjunction with theoretical techniques to locate the potentially troublesome regions of state space and explore their acceptability. It is shown in Part I that for general physical systems, x = f(x), all limit cycles are associated with equilibrium points that lie "inside" the limit cycles. Thus, if no equilibrium point exists in a region, then no limit cycle is contained in that region. Special properties of limit cycles and equilibrium points are discussed and illustrated. In Part II, equilibrium points are found analytically for spacecraft attitude control systems. A method is devised to determine stability near these equilibrium points. Then, instead of utilizing a uniform or random n-dimensional grid of computer initial conditions, a grid is concentrated around a few calculated points. Several practical examples of actual systems are presented. When control systems are viewed in this light, a high degree of confidence is gained from far fewer computer runs than previously needed.
