DESIGN of FUZZY SLIDING MODE CONTROL of CONTINUOUS STIRRED TANK REACTOR

Abstract

CSTR (Continuous Stirred Tank Reactor) is an important state of affairs in a chemical reaction and performs different kinds of searches in the fields of control and instrumentation engineering. The method (CSTR) utilizes various controllers to regulate the temperature and concentration. The presence of model uncertainty and external disturbances are two difficult problems in the control of a CSTR. The objective of this research was to control the temperature and concentration of the saponification reaction in a continuous stirred tank reactor (CSTR). This CSTR study also does a comparison of the response of the sliding mode controller and compares it with the fuzzy sliding mode process variable controller of CSTR in the presence of perturbations performed on it. A computational model of the CSTR has been developed, and a plant model has been designed. MATLAB/Simulink are utilized for simulation. Ultimately, the results of the simulation and comparison study demonstrate the continuously stirred tank reactor with FSMC controllers. The result for the product concentration of the saponification reaction was 0.639 mol/L and the product temperature was 297k in a fuzzy sliding mode controller performance steady state at 10 seconds, while the sliding mode controller result for the product concentration of the saponification reaction was 0.639 mol/L and the product temperature was around 300 k in a steady state at 304 seconds. The results obtained in this research may help control the ethyl acetate and sodium hydroxide saponification reactions in a CSTR.
