The temperature control of medical and biological ovens required a high precision controller. A Fuzzy-PD (Fuzzy-Proportional Derivative) controller is designed in this research for controlling the temperature of the heating system. The controlled heating system is a small laboratory oven used for biological experiments. The controller is designed using MATLAB version 7.14 program. SIMULINK environment of MATLAB program is used in designing the controller. The output response of the complete heating system for unit step input is obtained. The inputs and output membership function (MF) and also the surface viewer for the Fuzzy-PD controller are presented in this research. The simulation results show the good performance of the designed controller and its suitability and adaptability for such sensitive application.
