Process Control, Part 3: Beyond PID

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

The Process Control finale moves to a distillation column where separate loops can fight over the same process. Interaction, the relative gain array and decoupling explain why pairing measurements and manipulated variables matters. Model predictive control introduces a way to coordinate decisions while considering the plant ahead. The episode then revisits the operating story and emerging approaches, completing the series' journey from process dynamics to coordinated control.
