Abstract
On this article it’s detailed the characterization of a non linear process just as the pH neutralization process, inside this model it’s presented the transmitter sensor model an the final element of control, which is a commercial valve with specific characteristics that the process requires. Once finished the modeling stage on open loop, the transmitter sensor and the actuator it’s then designed a PID and a Fuzzy controller with their own performance criteria to select in which environment of operation each controller is better than the other. The designs and tests made are based on Fuzzy and PID controllers tuned with IAE and Dahlin criteria depending on the dynamics of the process.
