Process Control, Part 2: Feedback and PID in Depth

Deep End Era. Engineering with Sankalp · Oct 10, 2026 · 58m

Part two of Process Control looks closely at the controller most plants depend on: PID. Proportional, integral and derivative action are developed through their effects on a loop, then connected to tuning history and practical methods. Dead-time compensation, operating modes and transitions show why a mathematically plausible setting is only part of the job. The episode closes with an operational checklist that brings the controller, process and human operator into one discussion.
