Does Tuning a PID Controller Require a Bump Test?
It's generally accepted that tuning a PID controller requires some form of testing. Whether a step, bump, doublet, or pseudo random binary sequence, the test forces a change to the
What is Model-Predictive Control?
Model-Predictive Control (MPC) is advanced technology that optimizes the control and performance of business-critical production processes. So is Control Loop Performance Monitoring (CLPM) software. But if both help practitioners to
What is Cross-Correlation?
Do you remember when school kids simply lined up according to height before heading to the library or to gym class? Shortest in the front. Tallest in the back. A
How 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
What is the Value of Monitoring a Plant’s Control Loop Performance?
As might be expected there's growing interest in plant-wide loop monitoring capabilities. So much so that products in the category even have their own acronym now CLPM. In spite of
