What does a control signal do in an actuator?

A control signal in an actuator primarily functions to send commands that initiate mechanical movement. The actuator receives these commands, which are typically generated by a control system based on sensor inputs and desired setpoints. This interaction enables the actuator to perform actions such as opening or closing a valve, adjusting the position of a motor, or any other mechanical alteration as dictated by the control signal.

This process is essential in automated systems where precise control of mechanical components is necessary for optimal performance and efficiency. By using control signals, the actuator can respond accurately to the needs of the system, ensuring that processes are carried out in accordance with operational requirements.
