The blunting process of the residual water is viewed like a distributed parameters process. Starting from the system of equations that describe the working of the elements of the automatic control system (both ordinary differential equations and partial differential equations), the matrix of the partial derivatives of the state vector (Mpdx) is determined. Based on (Mpdx), the numerical simulation is made using Taylor series. The simulations are relevant both for the performances of the modeling-simulation method and for the performances of the automatic control system. References [1] M.
