Paper Title
PI Controller for PH Neutralization Plant

pH is a measurement of the acidity or alkalinity of a solution containing water. that is widely used in industry. Extreme nonlinearity and exhibition of severe interaction effects of multivariable pH processes makes it an appropriate test bed for assessment of controllers. To address these issues, a conventional PI controller is designed in this paper. In contrast with the majority of previous PI controllers in this field, the interaction effects of the process are considered in the design procedure. Simulation results are carried out to highlight the superior performance of the proposed controller in comparison to the previous ones.
