In particular, we compare the results obtained for the set-point and load disturbance step responses with those achieved with a Proportional-Integral-Derivative (PID) controller tuned by applying the well-known SIMC and AMIGO tuning rules. Different high-order processes are considered: self-regulating, distributed lag and non self-regulating. It is shown that, in general, the use of the double derivative (acceleration) action allows the integrated absolute error to be decreased without a decrement of the robustness and with a moderate increment of the control effort.eninfo:eu-repo/semantics/openAccess12 Matemáticas::1203 Ciencia de los ordenadores ::1203.17 InformáticaartículoPIDA controllersPID controllersTuningInternal Model Control
