Comparative study of strategies for fuzzy control P and PD applied to a pH plant

This work presents a fuzzy controller applied to a process of pH (hydronium potential) neutralization. The controller can be applied for the pH correction in waters with soap (wastewaters) and rainwaters, aiming at the reuse of such but not for drinking purposes. The controller has been implemented...

Description
Summary:This work presents a fuzzy controller applied to a process of pH (hydronium potential) neutralization. The controller can be applied for the pH correction in waters with soap (wastewaters) and rainwaters, aiming at the reuse of such but not for drinking purposes. The controller has been implemented from the "Mamdani" model with the analysis of two situations, one in which only the error is considered as the plant's input, and another where error and variation of error are considered for it. All simulations were performed in a MATLAB ® Simulink environment, and tested in an experimental microcontrolled plant using a PIC 18F4550, demonstrating the benefits of the fuzzy logic's application in this process.
