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}.
