Abstract
The paper presents a simple and systematic procedure for automatictuning of dead time compensating controllers (DTC). It integratesa simple identification experiment providing processcharacteristic numbers and a robust design method for an exactlydefined model family. This family contains all transfer functionshaving (a) the given a priori form of lag/dead time transferfunction (b) the experimentally obtained moment characteristicnumbers. The independently interesting result of this paper is theexplicit description of the value set for the model family.
