Webinar Recording: Simple Loop Tuning Methods and PID Features to Prevent Oscillations

 

This educational ISA webinar was presented by Greg McMillan in conjunction with the ISA Mentor Program. Greg is an industry consultant, author of numerous process control books, 2010 ISA Life Achievement Award recipient and retired Senior Fellow from Solutia Inc. (now Eastman Chemical).

 

Editor's Note: This is Part 3 of a three-part educational webinar series. To watch Part 1, click this link. To watch Part 2, click this link.

 

Part 3 (the final part) describes simple tuning methods and the PID features that can be used to prevent the oscillations that plague our most important loops and to achieve the desired degree of tightness or looseness in level control. A general procedure is offered and a block diagram of the most effective PID structure, not shown anywhere else, is given followed by questions and answers.
