How Do I Tune a Temperature Loop?
Temperature is one of the more common types of self-regulating - also known as non-integrating - processes used in industry. Like other self-regulating loops, temperature loops tend to naturally settle
What Sample Rate is Needed When Tuning PID Controllers?
Practitioners often apply simple guidelines when it comes to data collection requirements and controller tuning. These "rules of thumb" assure that sufficient data resolution exists when a given PID control
Default Out-of-the-Box Settings Prevent the PID Controller from Achieving its Goal
Tuning a PID controller doesn't have to be hard. Whether a practitioner chooses to tune control loops manually or with the help of software, the procedure is relatively straight forward
How Does the Derivative Term Affect PID Controller Performance?
Derivative is the third term within the PID. In mathematical terms the word derivative is defined as the slope of a curve. Seen in the context of strip chart data
How Often Should PID Control Loops be Tuned?
When it comes to PID control loops and the right time for tuning practitioners generally fall into one of two camps. There is the group that adheres to a philosophy
How Do I Calculate Dead-Time?
Adults can learn a thing or two from children. That's especially true when it comes to matters of time. Whereas adults view it as fashionable to show up to a
How Do I Calculate Gain? What Is the Difference Between Process Gain and Controller Gain?
Among practitioners who tune PID control loops manually most note their focus on calculating the Gain. Process Gain is a model parameter whereas Controller Gain is a tuning parameter. The
How Do I Tune a Level Controller?
Level controllers present challenges that are different from others. Although their presence is significant they lag behind Flow controllers in their overall share of the typical production facility's process control
Why is Zeigler-Nichols the Wrong Choice for Your PID Controllers?
In 1909 Henry Ford famously offered customers any color of his Model T automobile as long as their choice was black. Ford's "one size fits all" philosophy worked remarkably well
What Tools Are Available for Optimizing the CS 3000 and Centum VP DCS?
What have you done for me lately? That question directly influences the behavior of most everyone within a production facility. Face it, we operate in a meritocracy that has little
