Fundamentals of Process Control: Principles and Concepts offers an introduction to how engineers and technicians ensure that industrial processes, such as heating, mixing or pumping, are safe and efficient. It covers core concepts, including what a process is, how feedback control loops work and why measurements, valves and controllers matter. This book also provides practical tools, including proportional-integral-derivative (PID) tuning, cascade and ratio control and statistical methods for measuring and reducing variability. Later chapters introduce modeling and simulation, along with more advanced topics such as adaptive and fuzzy logic control, all grounded in clear examples and step-by-step explanations. Designed for learners and practitioners, this book strikes a balance between real-world applications and the key math and science necessary to understand and design control systems.
