What component typically manages the signals in an automatic control system?

In an automatic control system, the controller is the component responsible for managing the signals. The controller takes input signals, typically derived from sensors that measure process variables, and compares them to setpoint values to determine if adjustments are needed. It calculates the required output to maintain the desired system performance, making real-time decisions based on the data received.

The controller processes the error signals and generates appropriate control commands to actuators or other components, such as valves or motors, to adjust the process conditions. This feedback mechanism is crucial for maintaining stability and achieving desired outcomes in the controlled environment.

While sensors collect data and transmitters may send signals related to those readings, and valves act as the final control elements to modify fluid flow or temperature, it is ultimately the controller that orchestrates the entire process by interpreting inputs and directing actions.
