Intonation for a Proportional + Integral Industrial Process Controller, is a working tool for the Control engineer to establish the parameters of a controller based on the dynamic model of the process under study. The calculated parameters are the controller gain and the integral time constant. For the calculation, it has been considered for the dynamic, proportional, first-order integrative and first-order self-regulating models. With or without dead time. For models without dead time, the o
