(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.
