"Automatic control is a multidisciplinary subject covering topics of interest for electrical, mechanical, aerospace, chemical and industrial engineers. The objective of this text is to provide a comprehensive but practical coverage of the concepts of control systems theory. The theory is written in a straightforward uncomplicated way in order to simplify as much as possible, and in the same time classify, the problems met in classical automatic control. Each chapter includes an extensive section with formulas useful for dealing with the numerous solved problems that conclude the chapter. Finally, emphasis is given in the introduction of various simulation tools"--

"Using a practical approach that includes only necessary theoretical background, this book focuses on applied problems that motivate readers and help them understand the concepts of automatic control. The text covers servomechanisms, hydraulics, thermal control, mechanical systems, and electric circuits. It explains the modeling process, introduces the problem solution, and discusses derived results. Presented solutions are based directly on math formulas, which are provided in extensive tables throughout the text. This enables readers to develop the ability to quickly solve practical problems on control systems"--

Veloni (electronic computing systems, Technology Education Institute of Piraeus, Greece) and Palamides, with a Piraeus company, set out the fundamental concepts of control systems theory in a straightforward and simple manner for students and other readers encountering it for the first time. Among their topics are Laplace transforms, control system characteristics, root-locus analysis, the state-space representation of control systems, and simulation tools. Chapter-end formulas and problems are provided. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
