What is Variance? What Metrics are Useful in Identifying Process Change?
Ever walk onto the production floor and just sense that something was different? Whether it was something you saw, heard or even felt, a certain sixth sense kicked in and
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
What Training is Available for Process Control and PID Controller Tuning?
The latest report published by the Manufacturing Institute underscores the growing shortage of skilled labor here in the United States. Their 2014 study of skills and training Out of Inventory simply affirms
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
How Do I Perform an Effective Bump Test?
Bumping a process is a standard requirement when tuning a PID controller - whether you tune manually or with the help of software. And, either way, applying industry best-practices will
What Are My Options for Tuning a PID Controller?
Not all approaches to PID controller tuning are equal. Regardless of your approach a key to successfully tuning a controller is modeling the process dynamics accurately.
What is Non-Steady State Modeling or NSS Modeling?
Non-Steady State (NSS) Modeling is the ability to calculate an accurate process model when the associated data is oscillatory, is noisy, or has extensive Dead-Time. It's a highly valuable capability
How Do I Tune a PID Controller?
Techniques for modelling a process' dynamics and calculating tuning parameters are widely available. These approaches enable practitioners to tune controllers consistently and with reasonable results. At Control Station we know
