Modeling and simulation of the automatic control system of the residual water blunting process from a metallurgical factory

Abstract

This paper presents a method for the pH control of the residual water from a metallurgical factory. The blunting process is decomposed in two sub-processes connected in parallel, both viewed as distributed parameters processes and modeled through equations with partial derivatives. The mathematical model of the two sub-processes considers the delays introduced by the liquids circulation in the plant. The modeling-simulation procedure is an application of the matrix of partial derivatives of the state vector (Mpdx) method associated with Taylor series.
