Attitude stability eriteria are developed for "dual spin" spacecraft, which consist of two primary bodies capable of unlimited relative rotation about a common axis. Such vehieles, typified in existing hardware by the Orbiting Solar Observatory (OSO)

The analytical structures of alternative coordinate transformations for the variables that characterize the deformations of finite element models of flexible appendages on rotating spacecraft are examined. Particular emphasis is given to the truncati

A perturbation study is presented which investigates the influence of internal non-linear resonance on the angular motion of a gravity-stabilized satellite containing a spinning rotor and a damper. First-order conditions that induce resonance are dev

This paper seeks to improve the convergence properties of state estimators as used in spacecraft controller designs, when the linearized models upon which the estimators are based are subject to parameter errors, truncated modes, and neglected distur

An appraisal is made of past, present, and future applications of the general theory of multivariable control to the problem of spacecraft attitude control. It is noted that, while multivariable control has always been a characteristic of spacecraft

Equations of motion are derived for use in simulating a spacecraft or other complex electromechanical system amenable to idealization as a set of hinge-connected rigid bodies of tree topology, with rigid axisymmetric rotors and nonrigid appendages at

One of the most critical deficiencies of modern control theory in application to physical problems is the reliance of the theory upon the fidelity of the mathematical model of the physical system. The approach to model synthesis advanced here is the
