Ph Neutralization Process Control Using Linear Active Disturbance Rejection Control

Abstract

PH is the measure of acidity or alkalinity of a solution containing water, which has a wide usage in industry. The extreme nonlinearity and exposure to the effects of multivariable pH processes makes it an appropriate test bed for evaluation of controllers. To address these issues a Linear Active Disturbance Rejection Controller (LADRC)is designed in this paper. The simulation results are performed to highlight the outstanding performance of the proposed controller compared to the traditional PID controller.
