This book was released on 1966 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: A generalized analytical method is formulated for studying the motion and stability of a gravity-gradient satellite inertially connected with one or two gimballed damping booms which are assumed to be hinged at or very near the system center of mass; it is the relative motion between these connected bodies which affords a means of dissipating the librational energy. (An experimental satellite, called DODGE, employing the single damper boom will be launched in 1967). The equations of rotational motion are derived using Lagrange's general formulation, where the system center of mass is assumed to be in a circular orbit. Included are the effects of the gravitational restoring torques, the dissipative torques, and the gyroscopic torques that result from the coupling between the orbital angular velocity and the rotational motion in pitch-roll-yaw referenced to a local vertical frame. The equations are then linearized under suitable small angle assumptions to consider the motion and stability in the vicinity of the equilibrium point. The stability of the linear system is analyzed using both the methods of Routh-Hurwitz and Lyapunov's second or direct method. An extension of the linearized theory considers the stability of a particular nonlinear system, and examines the capture from zero inertial angular rate. Expressions are developed for the thermal deflections of the extendible booms and the torques resulting from the interaction of solar radiation forces with the bent booms. The stability criterion developed for the linear system is extended to consider the (assumed) continuously acting solar torques. This is achieved with an application of Malkin's theorem. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book explores CubeSat technology, and develops a nonlinear mathematical model of a spacecraft with the assumption that the satellite is a rigid body. It places emphasis on the CubeSat subsystem, orbit dynamics and perturbations, the satellite attitude dynamic and modeling, and components of attitude determination and the control subsystem. The book focuses on the attitude stabilization methods of spacecraft, and presents gravity gradient stabilization, aerodynamic stabilization, and permanent magnets stabilization as passive stabilization methods, and spin stabilization and three axis stabilization as active stabilization methods. It also discusses the need to develop a control system design, and describes the design of three controller configurations, namely the ProportionalIntegralDerivative Controller (PID), the Linear Quadratic Regulator (LQR), and the Fuzzy Logic Controller (FLC) and how they can be used to design the attitude control of CubeSat three-axis stabilization. Furthermore, it presents the design of a suitable attitude stabilization system by combining gravity gradient stabilization with magnetic torquing, and the design of magnetic coils which can be added in order to improve the accuracy of attitude stabilization. The book then investigates, simulates, and compares possible controller configurations that can be used to control the currents of magnetic coils when magnetic coils behave as the actuator of the system.
