Control engineering is a field of engineering which applies automation to the design of systems with desirable behaviors in controlled settings. By using sensors and detectors, the output performance of the controlled process is measured. Such measurement can provide corrective feedback to achieve the desired performance. Control engineering can have an essential role in diverse control systems, from flight and propulsion systems used in commercial airliners to household washing machines. Automatic control systems such as cruise control in a car are designed to perform without requiring human input. Modern control engineering integrates computer-automated design for controller system optimization, system identification, etc. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of control engineering. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included herein. This book is a resource guide for experts as well as students.
