Features: This book is a higher vocational college textbook for the electromechanical manufacturing major, combining electric drive with automatic control. The book is divided into three parts: Part 1 is the Basics of Electric Drive, Part 2 is Automatic Control, and Part 3 is Feedback Control Theory.
Part 1, the Basics of Electric Drive, focuses on DC separately excited motors and AC induction motors as the research objects, covering the fundamental theories of electric drive, analyzing the operating characteristics of motors in four quadrants, and introducing methods for selecting motor power ratings for three types of working conditions.
Part 2, Automatic Control, introduces both discontinuous control systems, including relay-contactor control circuits and sequence controller control circuits, and continuous control systems, such as motor generator control circuits and thyristor control circuits. It also explains the structure and working principles of various common control devices, providing typical circuit examples for each control circuit.
Part 3, Feedback Control Theory, covers the basic and fundamental knowledge of classical control theory, and introduces the basic methods of system compensation using frequency characteristics.
This book is rich in content, has a novel structure, and is concise in language. Each chapter includes summaries, exercises, or discussion questions, with solutions provided, making it convenient for readers to study independently. At the end of the book, there are technical parameters of some common electrical devices and the transfer functions of common regulators, which can serve as references for readers in practical work.
This book is also suitable for part-time universities and adult universities. Secondary vocational schools can also use it, and it is available for reference for electrical engineering technicians.
