Greatly expanded over the 1st Edition, this book takes stock of new developments in digital PID controllers and shares the authorsA experiences designing and applying controllers. Modeling methods, implementation details, and problem-solving techniques are presented that can improve loop performance and product quality. The book examines the auto-tuning and adaptation features of several commercial controllers. It discusses 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.
