Control Loops are the feedback mechanisms that work between a sensor or site control and a set of system or component settings-such as temperature or pressure. Understanding the various dynamics that come in to play when trying to control any active system can be complex and difficult, but this book seeks to make that effort much easier and more applicable to the day-to-day job site. The new edition will have greater coverage of on new software-driven control loop systems and control loop analytics. Readers will find: Review of control loop fundamentals, including PID controllers, loop dynamics and common tuning methods Coverage of the effects of various kinds of dynamics, including process, controller, measurement, valve and nonlinear dynamics New chapters on computer-aided control loop tuning methods and smart systems Summaries with useful control loop equations and algorithms

Control engineers, mechanical engineers and mechanical technicians will learn how to select the proper control systems for axial and centrifugal compressors for proper throughput and surge control, with a particular emphasis on surge control. Readers will learn to understand the importance of transmitter speed, digital controller sample time, and control valve stroking time in helping to prevent surge. Engineers and technicians will find this book to be a highly valuable guide on compressor control schemes and the importance of mitigating costly and sometimes catastrophic surge problems. It can be used as a self-tutorial guide or in the classroom with the book's helpful end-of-chapter questions and exercises and sections for keeping notes.
