Performance improvement for DC boost converter with fuzzy controller

This paper presents the improved performance of a fuzzy PD controller than a conventional PD controller to control DC-DC Converter. The experimentation in fuzzy domain using five and seven membership functions with the proposed input and output variables. A fuzzy controller can be implemented where linear control techniques fail. The experimental results of the proposed boost converter using fuzzy control are evaluated in comparison with PD controller. All the analysis and simulations were performed using MATLAB software. The comparison of both the results indicate that the fuzzy controller is able to obtain better dynamic response. The results confirm the capability of the control methods in the improvement of the above-mentioned converter functioning.
