A panel on Future Perspectives of PID Control of was the highlight of the second day of the IFAC PID’12 conference. The panel chairman was Professor Karl Astrom who is widely known throughout the control community for his many contributions in process control. Willy Wojsznis was the speaker on the panel from Emerson. The short …

Field experience using WirelessHART in control applications may be summarized in the following manner: WirelessHART measurements may be used in closed loop control applications. Window communications mode minimizes power consumption PIDPlus is a standard feature of DeltaV and works with standard WirelessHART devices. Standard DeltaV Tools support Simulation and Tuning. The performance of PIDPlus in …
Our profession is learned on the job by example and ad-hoc, incidental, or formal mentoring. Experienced APC and E&I engineers have largely left the building. In the new millennium we started a runaway reaction with an accelerating loss of expertise. Are we at a “point of no return?” Is the demise of our profession at …
To achieve best overall plant operation, it is often necessary to coordinate the operation of equipment in multiple process areas. In Chapter 16 of Control Loop Foundation – Batch and Continuous Processes, some examples are given where multi-loop techniques may be effectively used for such coordination. One of the examples from this chapter is power …

Deminar 11 “How to Setup and Adjust the Dynamic Compensation of Feedforward Signals” has been rescheduled from Wed Nov 17 to Wed Dec 1 (10 am CST not CDT). We will explore the adjustment of feedforward delay, lead-lag, and gain for the traditional PID and the smart PID for wireless (PIDPlus).
Emerson Exchange was held Sept 27th – Oct 1st, 2010 at the Henry B. Gonzalez Convention Center in San Antonio, Texas. Since Control Loop Foundation – Batch and Continuous Control was hot of the press, Mark Nixon and I took this opportunity to provide end users a detailed view of the book content. Jim Cahill …
