Publisher's Synopsis
In this book, systems described in terms of non-linear ordinary differential equations are treated. An attempt is made to convey to engineers and physicists the basic ideas of the dynamic behaviour of non-linear systems and to provide a view of some of the phenomena and solution methods in non-linear oscillations.;In this revised edition the author has updated the book, added a chapter on optimal control and new material on bifurcation theory and Hopf's theorem.;Applications of the theory may be found not only in classical mechanics, but also in electronics, communications, biology and other branches of science.
