What is an Actuator?
An actuator is a mechanical or electromechanical device that converts energy from a control signal into mechanical motion. In simpler terms, an actuator is a device that allows controlled movement or positioning.
Actuators need a control signal and a source of energy to bring about mechanical motion. Actuators use an energy source – such as electrical, compressed air, or hydraulic pressure – and a control signal that can be manual, an automatic electronic system, a fixed mechanical system, a software-run system, or a robotic control system.
What is an Actuator Control System?
An actuator control system is any electronic, electrical, or electromechanical system used to activate an actuator and control the direction, extent, and duration of its output. Actuator control systems may take the form of extremely simple, manually-operated start-and-stop stations, or sophisticated, programmable computer systems. The more advanced examples include servo systems that produce a wide range of actuator motion in response to the changing needs of the operational environment or process. This type of actuator control system utilizes an interface arrangement that assimilates feedback inputs from the process or mechanism and adjusts the actuator accordingly. Most actuator systems will, however, include at least a set of travel limits that prevent the actuator
