Folyamatvezérlésre, often translated as process control, refers to the engineering discipline that deals with controlling industrial processes. These processes can range from manufacturing and chemical production to power generation and environmental systems. The primary goal of process control is to maintain desired operating conditions, such as temperature, pressure, flow rate, or level, within a specified range. This ensures product quality, operational efficiency, and safety.

The fundamental components of a process control system include sensors, which measure process variables; controllers, which compare the measured variable to a setpoint and calculate an appropriate control action; and actuators, which implement the control action by manipulating the process. For example, a temperature sensor might measure the heat in a reactor, a controller would compare this to the desired temperature, and an actuator, like a valve controlling steam flow, would adjust the heat input.

Control strategies vary depending on the complexity and requirements of the process. Simple on-off control, proportional control, proportional-integral (PI) control, and proportional-integral-derivative (PID) control are common methods. Advanced techniques like model predictive control (MPC) are used for more complex systems. The development and implementation of effective process control systems are crucial for the economic viability and safe operation of many modern industries.
