Design And Analysis of Intelligent Controller For Temperature Control In CSTR System

Continuous Stirred Tank Reactor (CSTR) is one of the most important unit operations in chemical industries which exhibits highly non-linear behaviour and usually has wide operating ranges. Chemical reactions in the reactor are exothermic and require that energy can either be removed or added to the reactor to maintain a constant temperature. In this work, different controllers such as PID, Cascade, IMC controller, Differential Evolution, and Fuzzy Logic Controller have been evaluated. The objective is to control the temperature of CSTR in presence of the set point and analyzed which controller provides the most linear response.     Model design and simulation are done in the MATLAB/SIMULINK software. The response of the CSTR, which is observed with applying step input and improved by designing conventional and intelligent controllers.
