It is the scientific legacy of its promoter, Dr. Barceló who, after more than forty years developing this research project, has published his first book in the English language: New Paradigm in Physics. This book, as well as the bibliography and videos on this dynamic theory, is described in this article, which analyzes the behavior of rigid bodies subjected to accelerations by rotational movements, contributing new hypotheses of dynamic behavior.展开更多

Due to the inherent nonlinearities, couplings and uncertainties of an electromagnetic force model, the dynamics and control problems of them are difficult. A new modeling approach for relative motion dynamics with intersatellite force is proposed. To resolve these control problems better, a novel nonlinear control method for soft space electro-magnetic docking is proposed, which combines merits of artificial potential function method, Lyapunov theory and extended state observer. In addition, the angular momentum management problem of space electromagnetic docking and approaches of handling it by exploiting the Earth＇s magnetic torque are investigated. Finally, nonlinear simulation results demonstrate the feasibility of the dynamic model and the novel nonlinear control method.展开更多
