Short Educational Video on Transfer Function Identification: Software identification of First-Order Transfer Function parameters

Est. Reading: 2 minutes

Welcome to the fifth video from PiControl Solutions on practical Industrial System Identification and Process Control as we continue with a series of short, practical, and useful educational videos.

Even though we can visually identify First-Order Transfer Function parameters, we need to understand that it is sometimes not that simple to identify them as accurate and precise enough to be used in real processes, so there is a need for more advanced ways to identify them.

In this video, we will see how simple it is by doing it in the best system identification software PITOPS. We will first use our SIMCET software to simulate a few step tests of the first-order process and then import process data to PITOPS system identification software, as it would be done in the control room.

Make sure to give us a thumbs up and share it if you like it, and don’t forget to subscribe to our channel for more short and practical educational videos in the field of process control.

PiControl multivariable closed-loop system identification software called PITOPS can easily identify zero (integrating), first-order, and second-order transfer function parameters using historical plant data. It is also the only software product that performs truly closed-loop system identification with the secondary (cascade/slave) PID controllers while they are kept in Cascade (Remote) mode. No other competitor tool can do successful transfer function identification using data with PID controllers in Cascade modes.

PiControl real-time process control simulation software for training and education called SIMCET can simulate the real-time behavior of all transfer function models, even when they are impacted by large noise and continuous disturbances.
