Abstract: “This paper deals with the operation, mathematical modeling and controller design for the jacketed continuous stirred tank reactor. Ziegler Nichols tuned PID controller is poor in response for Non Linear processes. From the analysis of the process the IMC based controller is suits best for the CSTR.Controller is designed to control the reactant mixture temperature with in the reactor. The scheme is then design and tested using Matlab. The simulations are presented for PID and IMC controllers, and found IMC based Controller is best suits for the CSTR.”

Keywords: Nichols tuning Method, PID Controller, IMC based Controller and CSTR.
