Control of the pH neutralization process plays an important role in different chemical plants, such as biological, wastewater treatment, electrochemistry and precipitation plants. However, it is difficult to control a pH process with adequate performance due to its nonlinearities, time-varying properties and sensitivity to small disturbances when working near the equivalence point. For this purpose, modern process industries are increasingly relying on intelligent and adaptive control strategies such as fuzzy logic control. This research project deals with studies on the control of pH neutralization processes using fuzzy logic controllers. The fuzzy logic controller with a feedback control approach was implemented and a wide range of tests and experiments were conducted. Simulations results obtained revealed that fuzzy logic controller displays better closed-loop performance, in terms of set-point tracking and disturbance rejection.
