FEBRUARY 2010 – UNDERSTANDING DERIVATIVE IN PID CONTROL
The third factor in PID is the least understood. Derivative action can do good things, but when used improperly, it causes headaches. You’ve probably heard the expression, “a little knowledge…
Read MoreAUGUST 2016 – HOW TO TUNE PID LOOPS: TEMPERATURE CONTROL CHALLENGES
Temperature control applications can be broken into two main categories—fully continuous and semi-continuous (or batch). An example of a fully continuous temperature controller is a shell-and-tube heat exchanger. In this…
Read MoreFEBRUARY 2018 – THE IMPORTANCE OF ‘GOOD DATA’ WHEN TUNING PID LOOPS
Ask technicians and engineers about manually tuning PIDs. Their responses usually fall into one of the three different groups: 1) Some who will say it’s a “dark art” and won’t…
Read MoreWhat Relationship Exists Between Loop Monitoring and Predictive Maintenance?
Let’s say you take your car in for an oil change. The oil you select is rated for traveling a distance of 5,000 miles. In all likelihood the technician places a stickeron the car’s front window – a simple reminder of when the oil will be due for another change. In roughly 4 months this routine will be repeated.

Read MoreHow Do I Isolate the Root-Cause of Control Loop Performance Issues?
Finding controller performance issues in a typical production facility is not hard, but isolating and correcting their root-cause can present real challenges. Ask around stories abound of production staff who tune a PID control loop or re-pack a valve but ultimately fail to correct their problem. What may seem like the source of a performance problem is often little more than a symptom.
