Abstract
An event-based method to perform the set-point following task for second order processes with time delay (SOPTD) is investigated in this work. The aim of the research is to extend an event-based controller that has been tested previously in processes responding to the first-order with time delay (FOPTD) model. The controller is based on feedforward and feedback actions to do the two main tasks of a controller, set-point following and disturbances rejection, with an event triggered paradigm. This work is mainly focused on the feedforward part of the controller, with the goal of establishing a method to calculate the control signal and the conditions that must be satisfied to update it.
