Abstract

In this work, it is performed a comparison between the performance of PI and PI+CI compensators, in terms of a balanced index (servo/regulatory) based on the integrated absolute error (IAE). The plant is modelled by an integrating plus dead time (IPDT) process. The purporse of this work is to provide insight into the benefit of reset compensation both in servo and regulatory problems. This is accomplished by providing a tuning rule for the PI+CI, that allows to analyze the performance index in the compensator parameter space. The analysis done is independent of the process parameters.
