Motion Control is a sub-field of automation, encompassing the system or sub-systems involved in moving parts of machines in a controlled manner.
The main components involved:
- motion controller;
- energy amplifier;
- one or more prime movers or actuators.
Historically, motion control had its own controller and application software with motion-control algorithms to get the work done. Today, much of the motion control can be performed in the main control-system controller, if chosen carefully, but motion still requires specialty amplifiers/drives, motors, position feedback devices and precision mechanical linkage or actuators.
