THE CONTROL ALGORITHM FOR CONCENTRATION OF THE TARGET PRODUCT IN THE CHEMICAL REACTOR

Abstract

A chemicalreactor is one of the common apparatuses in chemical industry. Despite a large number of theworks related to automation and control of chemical reactors, the problem of synthesizing controlsystems that provide the maintenance of optimal modes of their operation remains practically unsolved.This is related to the principal feature of chemical reactors as controlled objects, namely,manifold, non-linearity, and multi-coupling. An outcome from this situation is to develop a physicaltheory of control, in particular synergetic control theory. The problem of analytical synthesis of nonlinear control law for the concentration of the target component in a chemical reactor has been solved.We use the methods of synergetic control theory, simulation methodsand methods of computational experiment. The paper deals with continuous stirred tank reactor equipped with a mechanicalstirrer and cooling jacket. The reactor operates in the polytropic mode. The multistep series-parallelexothermic process is carried out in the reactor. The objective of chemical reactor operationis to obtain the key product of specified concentration.
