Digital Control System
<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.
