Short Educational Video on Transfer Function Identification: Positive and Negative Model Process Gain

Est. Reading: 1 minute

Welcome to the third 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.

In the first two videos, we have seen the identification of zero and first-order transfer functions. There was a difference in positive and negative process gain. Sometimes students and young process engineers struggle with the question of can process gain be negative. Even though it sounds a bit counterintuitive, it is really a question of mathematics, and the answer is – yes, it can be negative.

In this short video we tackle this challenge once and for all, with a set of example simulations from our SIMCET software, with a simple visual and mathematic explanation.

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.

SIMCET is a real-time, online PID tuning simulator for practice and testing of tuning skills. Tuning PIDs in SIMCET is exactly as if you are tuning loops in a real plant, therefore, it is a great way for inexperienced technicians and engineers to gain knowledge and confidence in PID tuning.
