الملخص الإنجليزي

Fuzzy logic control (FLC) systems have been tested in many technical and industrial applications as a useful modeling tool that can handle the uncertainties and nonlinearities of modern control systems.

The main drawback of the FLC methodologies in the industrial environment is challenging for selecting the number of optimum tuning parameters.

In this dissertation, a method has been proposed for finding the optimum membership functions, output gain and inputs gain of a fuzzy system using genetic algorithm (GA).

A synthetic algorithm combined from fuzzy logic control and GA is used to design a controller for DC-DC converter.

To exhibit the effectiveness of proposed algorithm, it is used to optimize the triangle membership functions of the fuzzy model DC-DC converter system as a case study.

It is clearly proved that the optimized fuzzy controllers provided better performance than a fuzzy model for the same system in terms of settling time, steady state error and ripple voltage at the output response.

The evaluation of the output has been carried out by software simulation using MATLAB Simulink
