Robust Stabilization of a Continuous Stirred Tank Reactor Model

Abstract

The main goal of this contribution is to outline an approach to robust stabilization of a continuous stirred tank reactor (CSTR) by means of PI controller. The linearized mathematical model of the CSTR with an exothermic reaction is supposed in the form of the fourth order interval system and its robust stabilization is based on combination of a method for calculating/plotting the stability boundary, the sixteen plant theorem and an algebraic approach to control design. The validity of the technique is verified on a simulative example of CSTR control.
