The time spent residing on this column is time well spent if you want to become famous for improving process performance with the side benefit of becoming best buds with the process...
Particularly confusing is variability that seems to come out of nowhere and then disappear. There are not presently good tools to track down the sources because it turns out most...
There are a lot of misconceptions on what is the turndown capability of measurements and final control elements (e.g., control valves and variable frequency drives). Here is a...
There is a common mistake made in the sizing of most control valves. The intentions that lead to this mistake may be good but the results are insidiously bad. While you would ...
Here is the Sixth part of a point blank decisive comprehensive list of what we really need to know in a detailed attempt to reduce the disparity between theory and practice. Please...

Here is the second part of a point blank decisive comprehensive list of what we really need to know in a detailed attempt to reduce the disparity between theory and practice. ...
I had an awakening as to the much greater than realized disconnect between what is said in the literature and courses and what we need to know as practitioners as I was giving...
In many publications on process control, the common metric you see is integrated absolute error for a step disturbance on the process output. In many tests for tuning, setpoint...
Having the blind wholesale goal of reducing variability can lead to doing the wrong thing that can reduce plant safety and performance. Here we look at some common mistakes made...
Inverse response, negative resistance, positive feedback and discontinuities can cause processes to jump, accelerate and oscillate confusing the control system and the operator...
The operator is by far the most important person in the control room having the most intimate knowledge and “hands on” experience with the process. Engineers who are most successful...
The ISA Mentor Program, started by Greg McMillan and Hunter Vegas in 2011, is extending its invitation to prospective protégés/protégées and resources to include any engineer ...
