This Paper converses the design of a nonlinear feedback controller for temperature control of continuous stirred tank reactors (CSTRs) which have strong nonlinearities. Continuous Stirred Tank Reactor (CSTR) is one of the common reactors in process industries in which various process variables like temperature, concentration have to be controlled. The reaction temperature is the most important process parameter in the CSTR process, and the control of reaction temperature quality is closely related to the production efficiency and economic benefit. Accordingly, it is requisite to introduce a control mechanism that will make the proper changes in the process, in order to have the desired operation of the chemical plant. During the time of exploration, a number of tuning methods such as Ziegler-Nichols, CohanCoon, Tyreus Luyben for suitable PID controller and advanced controllers like Fractional Order PID (FOPID), Internal Model Controller (IMC) has also examined to optimize the temperature controller for CSTR system. A simulation result on the CSTR system is presented to show the efficiency of the various controllers and tuning rules. Performance indices for various tuning methods of the controller are also designed, compared, analyzed and presented using MATLAB and an attractive control method with a suitable advanced controller has been identified.
