This book is devoted to the study of the dynamics of rotating bodies with cavities containing liquid. Two basic classes of motion are analyzed: rotation and libration. Cases of complete and partial filling of cavities with ideal liquid and complete filling with viscous liquid are treated. A method is presented for obtaining relations between angular velocities perpendicular to main rotation and external force momentums, treated as control. This work will be of interest to professionals and researchers at universities and laboratories specializing in problems of control for hybrid systems and aerospace/mechanical engineering, as well as to under-/postgraduates with this specialization-- Provided by publisher.
