Abstract- Variable speed drives are nowadays growing and varying very fast. Drives expanse depends on progress in different part of science like power system electronic control methods and so on. Because the fuzzy logic techniques can be used to control any type of system. The mathematical background and initial assumptions on which the conventional method relies on. On the other hand the fuzzy control is based on fuzzy logic a logical system that is much closer to the human thinking and natural language compared with the classical control methods. Usually the synthesis of controller includes both the controller type selection and the adjustment of its parameters. In some cases the controllers type might be more complex than a PI D type controller. In all the cases the tuning problem must be satisfactorily solved. These types of situations can be solved more easily with a fuzzy controller which has made possible the establishment of intelligent control. This study presents efficient method for speed control of a separately excited D.C motor using fuzzy logic control FLC. However the controllers based on fuzzy logic theory are used only in simple configurations and their analytical knowledge is still poor. In this paper a quantitative and qualitative study of fuzzy controller is made.
