Abstract

The common problem in pH reactors to determination and control and concerning chemical-based industrial processes by virtue of the non-linearity observed in the titration curve. The pH control had always drawn attention of chemical engineers because of its connotation in various fields as medicine, where the effect of pH on the enzymes and blood is acutely investigated, and the industry which is perturbed with manufacturing of textile dyes, and bleach products. The high non-linearity in pH is an immeasurable challenge in process control and it cannot be effective controlled by the linear PID controller. Hence advanced tuned PID controllers are best suited which are designed and developed for a pH control process in order to control the plant to the desired set point with high quality performance over the entire operating range. The mathematical model of pH process is obtained to ensure the dynamic modifications and stability enhancement. The ZN tuned PID, automatic tuned PID and PSO PID controller is implemented in simulation. The simulation is done using MATLAB software and the results are compared.
