Turning of Industrial Control Systems – Armando B. Corripio, Michael Newell – 3rd Edition


A PRACTICAL AND SYSTEMATIC APPROACH TO TUNING In this third edition, the authors’ aim has been to simplify and demystify the procedure of tuning based on their successful tuning work in oil refineries. A new chapter has been added on the use of auto-tuning currently available in most current computer control . The authors have used this software whenever possible to carry out the dynamic testing of the as it is less disruptive of than doing the tests manually.

They have also used the tuning results to guide them but always using the principles presented in the book to evaluate them. All of the example responses have been generated using software to illustrate the tuning and show the differences between -tuning controllable versus dead-time dominated loops averaging versus tight level control -cascade control versus simple feedback control of a jacketed reactor -feedforward control versus simple feedback control -decoupler control versus simple feedback control of a blender.
