Abstract :
A solution for the pH control of the residual water in an industrial blunting system is proposed. The technological process associated to the blunting system is decomposed in four sub-processes connected in series and in parallel, each of them being a distributed parameter one. The mathematical models of the sub-processes are expressed using partial differential equations. Both this procedure and the advanced structure of the control system generate very high control performances. For the numerical simulation of the control system, a numerical method based on the Matrix of Partial Derivatives of the State Vector, associated with Taylor series is proposed. This method permits the numerical simulation of the systems that include in their structure distributed parameter processes. The conducted simulations proved high accuracy of our original method.
