Intelligent Self Tuning ANFIS Temperature Regulator for Plastic Extrusion System

Temperature control in plastic extrusion plant is a crucial process. The first order temperature control system comprises of coupling effects, long delay time and large time constants. The model is controlled with three unique control techniques. The first technique is PID control;the second is fuzzy logic control while the third control technique is Adaptive Neuro Fuzzy Control. ANFIS controller is most powerful approach to retrieve the adaptiveness in the case of nonlinear system. While designing a controller it must be first tuned to the system. The tuning synchronizes the controller to the controlled variable and make the process to kept at its desired operating condition. Relatively ANFIS controller gives improved performance than PID & FUZZY controller as shown by simulink of Matlab.
