Webinar Recording: Feedforward and Ratio Control

The post Webinar Recording: Feedforward and Ratio Control first appeared on the ISA Interchange blog site.

This educational ISA webinar on control valves 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).



Feedforward control and ratio control that preemptively correct for load disturbances or changes in leader flow are greatly underutilized due to the lack of understanding of how to configure the control and determine the parameters needed. This webinar provides key insights on how feedforward control often simplifies to ratio control. It also explains how to identify the parameters so that the feedforward or ratio control correction does not arrive too late or too soon and the correction has the right sign and value to cancel out the load disturbance or achieve the right ratio to the leader flow.
