The Practical Guide to Control Loop Optimization. Tune PID controllers more effectively, in less time, and ensure long-term loop stability. Here is your complete reference for improving control loop performance, solving process control problems, and designing control strategies. You will refer to this guide again and again. You will discover how easy it is to: Understand PID controllers, their control actions, settings, and options; Identify process dynamics and their effects on loop performance and controller tuning; Get the best possible performance from a control loop; Tune controllers differently to achieve specific control objectives; Identify the root cause (or causes) of poor control performance; Use techniques like linearization and gain scheduling to ensure consistent loop response and long-term stability; Design and optimize control strategies like cascade, feedforward, and ratio control to improve control performance and reduce variability; Monitor loop performance and pinpoint control problems.
