This video presents the problem statement (basic process, regulator, and closed-loop structure) needed to control an unstable 1st-order process (inspired by a bioreactor) via a proportional-integral (PI) regulator.
In this first video, emphasis is made on a ‘heuristic’, ‘trial and error’ design; fine-tuning and refinements regarding anti-windup and two-degree-of-freedom setpoint preprocessing are also discussed to achieve a reasonably good response in both setpoint tracking and input disturbance rejection tasks.
The theory justifying the observed performance will be discussed in depth in
