PID Controllers: Theory, Design, and Tuning, 2nd Edition

Greatly expanded over the first edition, this book addresses new developments in digital PID controllers and shares the authors’ experiences in designing and applying controllers. It presents modeling methods, implementation details, and problem-solving techniques to improve loop performance and product quality; examines the auto-tuning and adaptation features of several commercial controllers; and provides measures for dealing with specific challenges, such as reset windup, long process dead times, and oscillatory systems. The authors also recommend design methods and tuning rules that consider factors such as load disturbances, measurement noise, model uncertainty, and set point response.
