Process control is the automated system of monitoring and adjusting engineering variables to keep an industrial operation stable, safe, and efficient. Because the phrase “process management” can apply to different industries, I am assuming you are asking about industrial automation and chemical/mechanical engineering process control. This foundational blueprint covers how factories, refineries, and water treatment plants run on autopilot. Core Concept: The 3-Step Control Loop
Every basic process control system (BPCS) relies on a continuous loop that executes three fundamental tasks: Measure (The Sensor): Collects raw environmental data. Decide (The Controller): Computes deviations from the goal.
Act (The Regulator/Actuator): Executes physical changes to fix deviations.
A classic everyday example of a process control loop is a home thermostat. It measures the room temperature, decides if it matches your target setting, and acts by turning the furnace on or off. Essential Terminology
To understand system controls, you need to know these four operational variables: Process Control – Understanding the Basics
