Control PID de procesos autoregulados e integrantes sintonizados con el método lambda.

Abstract

This work presents the implementation of a didactic tool to determine the value of the constants of a PID controller through the lambda method, also known as IMC (Internal Control Method). Such a tool can be used to start a process or ratify the current values of the constants of the controller since the wear out of the processs elements affects its dynamics, being necessary to update them frequently. In order to validate the tool, tests were carried out on an integral process and a self-regulating one. The comparison of constant values applying conventional control strategies such as PID and lambda method, as well as the response of the process to similar changes, as set point or disturbances is presented. The obtained results determining that through the lambda tuning the control is fast and stable.
