Convergent control of the residual water blunting system used in metallurgy

In this paper, a solution for the pH control of the residual water is presented. The blunting process is treated as a distributed parameter one, its model being expressed using equations with partial derivatives. The modeling-simulation procedure is based on the matrix of partial derivatives of the state vector associated with Taylor series, method that assures a very high accuracy. The convergent control structure is designed in order to obtain higher performances than in the case of using a simple control structure. The differences between the responses of the two control structures are presented in the simulations chapter, using comparative graphs.
