This paper describes three important aspects: design, simulation and Implementation of Adaptive Neuro fuzzy system applied to the temperature variable of a thermal system with a range of 250C to 500C.An Adaptive Neuro Fuzzy Inference System (ANFIS) based controller is proposed for water temperature control. The generation of membership function is a challenging problem for fuzzy sytems and the response of fuzzy systems depends mainly on the membership functions. The ANFIS based input – output model is used to tune the membership functions in fuzzy system. Experimental results are compared with the conventional PID Controller and Neural Network Controller. All the controllers are tested in various operating conditions and varying set point changes and also for disturbance rejection. This shows that better performance can be achieved with ANFIS tuning.
