Features: This book can not only serve as a textbook for chemical engineering and technology majors in higher education institutions but also for related majors in petrochemical, light industry, forestry, metallurgy, and other fields. It primarily introduces the basic knowledge of automatic control systems in industrial production processes and explains the various fundamental components of automatic control systems, including controlled objects, measuring elements and transmitters, display instruments, automatic control instruments, actuators, etc. Building upon simple and complex control systems, it also covers modern control systems and computer control systems (such as DCS, fieldbus, etc.). Finally, it presents typical control schemes for chemical unit operations in chemical production processes. The third edition of this book aligns with the characteristics of teaching reform in various institutions, emphasizing the update and optimization of course content. It removes certain outdated content from the second edition (e.g., pneumatic instruments and some older models of instruments), revises some cumbersome or less frequently encountered content by technicians (e.g., certain instrument structures and circuit diagrams), and incorporates a wealth of new content reflecting the current level of automation. It particularly provides a concise yet thorough introduction to the application of computers in process control and various modern control systems.
