Abstract

This work deals with using a method of artificial intelligence, mainly the generic probabilistic meta-algorithm can be used in such a difficult task which is analyzed and control of dynamical systems. Simulated annealing (SA) is used in this investigation. The adaptive control system was used in simulations with optimization by Simulated Annealing and the results are presented in graphs.

Mathematical Problems

Consider a CSTR with the first order consecutive exothermic reaction according to the scheme and with a perfectly mixed cooling jacket. Using the usual simplifications, the model of the CSTR is described by four nonlinear differential equations [6][7].

The subscripts are denoted (.)r for the reactant mixture, (.)c for the coolant, (.)i for feed (inlet) values and the superscript (.)s for steady-state values. The reaction rates and the reaction heat are expressed as
