IMC control of fast process: constant Q [internal model control]

This video discusses IMC control of a "fast" process where its open-loop settling time is already fast enough for a given application, and we don't wish to speed it up in closed-loop to, for example, avoid unnecessary actuator oversizing. In this case, the explicit IMC is easy, it is simply a question of proposing {Q=1/dcgain(G)}. When transformed to a conventional regulator (implicit IMC) with K=Q/(1-GK), it results in a closed-loop integral action controller, as the theory predicts. So, in the event of input and output disturbances and setpoint changes, it exhibits a closed-loop dynamics that achieves zero error with closed-loop poles in the same place as the open-loop ones, which was our ultimate goal. ________________ PDF/code/notes at: http://personales.upv.es/asala/YT/V/i... #imc #controlengineering #matlab _________________ Antonio Sala Full collection of videos at: http://personales.upv.es/asala/YT/ind...
