Process Control, Part 1: Dynamics from First Principles

Deep End Era. Engineering with Sankalp · Oct 10, 2026 · 1h

Part one of Process Control begins with a tank that will not settle and asks what determines a process response. Gain, first-order lag, dead time and integrating behavior provide distinct ways to describe the dynamics behind a trend. Noise and sampling complicate what the controller can observe. The episode then examines how closing the loop changes the system, preparing the foundation needed to understand and tune feedback in part two.
