Abstract: The Continuous Stirred Tank Reactor (CSTR) is the important topic in process industries, its stable and efficient operation is important to the success of an entire process. It is one of the optional machineries available to mimic and maintain the deep sea conditions such as pressure, temperature, pH etc in the laboratory to study environmental effects. This paper presents the design of suitable controller and tuning methods to optimize the system performance for a hyperbaric reactor system. Simulation and result comparison is carried out using MATLAB &SIMULINK. Different controllers are examined to optimize the temperature control for environmental CSTR system. The simulation result on the environmental CSTR system is presented to show efficiency of various controllers.

Keywords: High pressure rated CSTR system, Process modelling, PID Controller, Fuzzy PID Controller.
