Abstract:

This report summarizes a body of research dealing with the nonlinear control theory of complex mechanical systems. The principal focus is on the dynamics of rotating systems with uncontrolled degrees of freedom, and we treat specific model problems of pointing, shape, and orientation control of complex spacecraft in a zero gravity environment. We also examine the dynamics of rotating kinematic chains. The list of references in this report cites all our major contributions to the literature of rotational mechanics. Two papers in particular-Rotational Elastic Dynamics and Equilibrium Mechanics of Rotating Systems form the principal basis for the present report. Indeed, these papers are reproduced here with occasional remarks and comments inserted regarding very recent developments in the field. Author KR
