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.
