Process control refers to the methodology of regulating and influencing the behavior of a process to achieve desired outcomes. It involves measuring process variables, comparing them to desired setpoints, and implementing corrective actions through control loops. These control loops can be manual or automated. Automated systems typically employ sensors to gather data, controllers to process this information and make decisions, and actuators to implement the necessary adjustments. The goal is to maintain stability, optimize performance, ensure safety, and meet product quality specifications.

Common process control strategies include feedback control, where the system reacts to measured output deviations, and feedforward control, which anticipates disturbances and acts preemptively. Proportional-Integral-Derivative (PID) control is a widely used algorithm that combines proportional, integral, and derivative terms to adjust the control output. Advanced control techniques like model predictive control (MPC) utilize mathematical models of the process to optimize control actions over a future time horizon. Process control finds applications in a vast range of industries, including manufacturing, chemical processing, power generation, and environmental management. Effective process control is crucial for operational efficiency and economic viability.
