This work is intended as a textbook to be used in M. Sc. and final-year B. Sc. courses in control theory of nonlinear dynamical (deterministic) systems. While it focuses on the lectures given by the author to postgraduate students in Control Systems, it also contains useful comments on more advanced topics e.g.: singular points, limit cycles (Poincaré-Bendixson theorem), strange attractors and chaos, and so one. The book consists of: Preface, Introduction, 7 chapters, two appendices, References and Subject Index. Besides the more advanced topics above, included are: the linearisation of nonlinear functions, oscillations in feedback systems, forced systems, Lyapunov’s methods, Popop’s method, input-output methods, discrete-time systems and so one. The book also contains a number of significant worked examples which are treated from a control engineering viewpoint. At the end of the chapters 2-7 the author has also included interesting exercises (whose solutions are provided in Appendix 2). The general results, e.g. Poincaré-Bendixson theorem, are presented without proof, but information regarding the sources of the corresponding material are given in Appendix 1.
