Preface

The oscillatory processes can be divided into the following types: free, forced, parametric, and self-excited oscillations. In addition, two or more oscillations can interact in the same oscillatory system. This fact is of important scientific and practical interest. It is well known that oscillators are widely used in engineering and science for various applications such as signal generation, modeling, and design purposes.

This book presents a selection of papers on the dynamic behavior of oscillatory systems dealing with physical systems modeling, as well as discusses the physical phenomena involved and the methodology used to deal with them. It also explores the possible applications of oscillators to practical problems in engineering and science.

The book contains eight chapters organized into three sections.

Acknowledgments are due to all the authors, co-authors, and reviewers for all their time and collaboration and for their interest and enthusiasm in supporting this book.

The authors also acknowledge Mrs. Ana Cink at IntechOpen for her help throughout the publication process.
