<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 DCSSampleSfeedback 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 methodSSuch aSdifference equationS, {Laplace tranSformS}, {z tranSfer functionS}, {State Space modelS} and State tranSition matriceS.
