In control terminology, a device that converts electrical control signals into physical movement is called an ______.

In control systems, the component that converts electrical control signals into physical movement is an actuator. It sits at the end of the control loop and turns the electrical command into real motion or force to move a mechanism, valve, or load. Sensors measure physical quantities and feed signals back; controllers process those signals to determine what action is needed; a transducer is a broader term for devices that convert one form of energy to another, but this specific description—turning an electrical command into motion—points to an actuator. Examples include motors, hydraulic cylinders, and pneumatic pistons.
