Digital Control System

(DCS) A digital computer used for real-time control of a dynamic system, usually in an industrial environment, possibly as part of a Supervisory Control and Data Acquisition (SCADA) system.

A DCS samples feedback from the system under control and modifies the control signals in an attempt to achieve some desired behaviour.

Analysis of such digital-analogue feedback systems can involve mathematical methods such as difference equations, Laplace transforms, z transfer functions, state space models and state transition matrices.
