Commonly used terms in the Electrical industry.

compensation
(1) operations employed in a control scheme to counteract dynamic lags or to modify the transformation between measured variables and controller output to produce prompt stable response.
(2) the alteration of the dynamic behavior of a process by the addition of system blocks. These are usually connected in cascade with the original process on either its input or its output variables, or both. See also compensator, pre-compensator and post-compensator.
reactive compensation
process of counteracting the reactive component of a device by means of capacitors and inductors. Both series and shunt compensation are prevalent.
