—This paper presents the design of a nonlinear feedback controller is analyzed for temperature control of continuous stirred tank reactors (CSTRs) which have strong nonlinearities. Consequently, we need to introduce a control mechanism that will make the proper changes on the process to cancel the negative impact that such nonlinearities may have on the desired operation of chemical plant. A method for adaptive control of a continuous stirred tank reactor with output temperature constraint is developed. The controller is robust to modeling errors and random disturbances occurring in the system. The controller design is analyzed for this situation we use two controller Adaptive and PID and analyzed which controller provide most linear response, The basic PID controllers have difficulty in dealing with problems that appear in complex non-linear processes Simulation studies give satisfactory results.
