Abstract


In this paper, a solution for the pH control of the residual water, at the overflowing point from a blunting system, is proposed. The modeling-simulation of the blunting process and of the proposed feed-forward control structure is based on the matrix of partial derivatives of the state vector, associated with Taylor series. The approached control strategy generates much better results than in the case of using a simple control structure, fact that results from the comparative simulations presented in the “Simulations Results” chapter. Also the modeling method offers the advantage of the possibility of the simulation and control of the pH value in each point from the neutralizing tank’s volume. Another singularity of this paper is the inclusion of a distributed parameter process (modeled through an equation with partial derivatives) in a control structure.
