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 option is given to set the response time and see the behavior graph of the closed loop for a unit step step at the desired value.

For the case of the models with dead time, a tuning factor is established, and for the first order model with dead time, 2 more tuning options are presented, such as Zieglers-Nichols and the one based on the integral of the absolute error. time-weighted.

The calculated tuning parameters are suggested values ​​and depend on the model introduced and the actual conditions of the process, so it depends on the experience of the engineer at the time of application.

The formulas used are our own, except of course the Ziegler-Nichols and IATE ones.
