Abstract

Part 1 The mathematical pendulum as an illustration of linear and non-linear oscillations - systems which are similar to a simple linear oscillator: Undamped free oscillations of the pendulum damped free oscillations forced oscillations. Part 2 Liapounov stability theory and bifurcations: The concept of Liapounov stability the direct method of Liapounov stability by the first approximation the Poincare map the critical case of a conjugate pair of eigenvalues simple bifurcation of equilibria and the Hopf bifurcation. Part 3: Self-excited oscillations in mechanical and electrical systems analytical approximation methods for the computation of self-excited oscillations analytical criteria for the existence of limit cycles forced oscillations in self-excited systems self-excited oscillations in systems with several degrees of freedom Part 4 Hamiltonian systems: Hamiltonian differential equations in mechanics canonical transformations the Hamilton-Jacobi differential equation canonical transformations and the motion perturbation theory Part 5 Introduction to the theory of optimal control: Control problems, controllability the Pontryagin maximum principle transversality conditions and problems with target sets canonical perturbation theory in optimal control.
