Digital Control System definition 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
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.
