What is typically used to position an actuator in a control system?

Positioning an actuator within a control system primarily relies on the output signal from an electronic controller. This signal provides the necessary instructions to the actuator, enabling it to adjust its position according to the requirements of the system. The electronic controller processes information from various inputs, which may include sensor data, and then produces an output signal that precisely dictates the movement or position of the actuator.

The output signal can be in the form of voltage or current, which directly governs how far and in which direction the actuator should move, thereby ensuring that the system responds accurately to control inputs and maintains desired operating conditions. This approach allows for precise control and automation within various applications, enhancing efficiency and reliability in system operations.
