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 what the acronym suggests in terms of CLPM being an established technology, questions about its value persist.
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 save you significant time and money.
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.
