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.
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 when tuning difficult PID loops, and it was pioneered by Control Station.
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 a little about this topic as we’ve been sharing these techniques for decades and innovating software-based solutions that deliver even better results.
Control Station is evolving. Over the years our company and the way we communicate has changed. This blog is our latest initiative to improve our communication with practitioners. As with most things we thought it would be best to begin by answering some basic questions like “Who we are?” and “What we do?”
