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.
