Motion control systems are extensively used in a variety of fields for automation purposes, including precision engineering, micromanufacturing, biotechnology, and nanotechnology.
[1] The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators.
In open loop systems, the controller sends a command through the amplifier to the prime mover or actuator, and does not know if the desired motion was actually achieved.
Typically the position or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or electric motor, generally a servo.
Motion control is widely used in the packaging, printing, textile, semiconductor production, and assembly industries.
