Welcome to the latest 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.

We have seen that it is not possible to completely identify all parameters of the second-order transfer function by just visual inspection, therefore, software identification is needed. Second-order processes on step tests, react in two shapes: Wavy shape and S-shape. In this short educational video, we will show you how PITOPS handles both of these cases very quickly and easy identifies all parameters of the second-order transfer function.

Make sure to give us 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. For more info on PITOPS please visit:

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.
