returstyring
Returstyring, or return control, is a form of feedback control used to regulate a system by influencing its input based on measurements taken from the return path or cycle of the process. In a typical returstyring setup, sensors monitor a process variable that reflects the state of the system after a process step or along a return stream, such as temperature, flow, pressure, or energy recovered. The controller compares the measured value with a desired setpoint and produces a control signal for an actuator that adjusts the input to drive the variable toward the setpoint. The result is a closed-loop system that aims to minimize error, improve stability, and increase efficiency.
Key elements of returstyring include sensors, a controller, actuators, and a defined feedback path. Variants commonly
Applications of returstyring span multiple domains. In process industries, it is used to regulate return streams
