Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner.

The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators.

Motion control may be open loop or closed loop.

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.

Typical systems include stepper motor or fan control.

For tighter control with more precision, a measuring device may be added to the system (usually near the end motion).

When the measurement is converted to a signal that is sent back to the controller, and the controller compensates for any error, it becomes a Closed loop System.

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

Instrumentation is a collective term for measuring instruments used for indicating, measuring and recording physical quantities.

An actuator is a component of a machine that is responsible for moving or controlling a mechanism or system.

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action.

Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.
