Control Loop Foundation: Process Control Guide Control loops are the building blocks of automation. They maintain variables like temperature, pressure, and flow at a desired setpoint. ⚙️ Core Components The actual measured value. Setpoint (SP): The target value you want to achieve. Controller (PID): The "brain" that calculates the error. Final Control Element (FCE): Usually a valve or motor. 🔄 Continuous Process Control Continuous processes run 24/7 with steady-state conditions. Objective: Minimise variance around a fixed setpoint. Feedback Loops: Most common; adjusts based on past error. Control Loop Foundation: Process Control Guide Control loops

SP often changes based on a profile.

Key metrics documented in any advanced PDF: Setpoint (SP): The target value you want to achieve

While batch and continuous processes have distinct personalities—one seeks a constant steady state, the other follows a dynamic trajectory—their . Both rely on the sensor-controller-actuator triad. Both require meticulous PID tuning. Both fail due to integral windup and poor valve maintenance.
