Fuzzy Based Temperature Controller For Continuous Stirred Tank Reactor

S.Boobalan, K.Prabhu, V.Murali Bhaskaran

Fuzzy based PID controller is implemented to control the reactant temperature of a continuous stirred tank reactor(CSTR). The plant is modeled mathematically for the normal operating condition of CSTR. Then the transfer function model is obtained from the process. The analysis is made for the given process for the design of controller with conventional PID (trial and error method), Ziegler Nichols method and Fuzzy logic method. The servo response is obtained for all the above three methods and traced different operating condition of temperatures. The servo response of Fuzzy based PID controller has given better setpoint tracking capability than the Ziegler-Nichols method and conventional PID method.
