Fuzzy logic control technique is one of the modern control methods for decision making of the systems. By using fuzzy logic approach, many different decision options can be applied to the systems. However, this approach needs some knowledge about the system conditions. In this conference paper, fuzzy logic controller approach is applied to a fixed wing (Ultrastick-25-e) unmanned aerial vehicle (UAV) which exists in the literature and aerodynamic parameters needed for dynamic equations are obtained from the literature. According to different fuzzy rules and membership functions, fuzzy inference system is obtained for different aircraft dynamics such as roll, pitch, yaw and altitude etc. characteristics. Responses of the dynamic state variables and their outputs are investigated individually by using transfer functions and fuzzy logic rules. In this analysis, gust disturbance is not taken into account for UAV dynamic equations in this level of analysis. Obtained results will be compared to previous and future studies of UAV control.
