How to Design a Process Control System

Practical process control system design is not applied mathematics. It is about how to put instruments and actuators on the P&ID and FDS for the plant, which are sufficient to make the plant approximate steady state (or more likely a number of reasonably steady states). It is also linked inextricably to process design in such a way as to work in concert to yield an inherently safe, controllable, and error-tolerant plant.
