Different Autopilot Systems Design For a Small Fixed Wing Unmanned Aerial Vehicle

The aim of this study is to design an autopilot system for Unmanned Aerial Vehicle (UAV) in a small size and to compare theefficiency of the systems designed with different methods. For this purpose, linearized equations of motion for a small size UAV hasbeeen firstly obtained. Then the state space equations are used to check the stability characteristics of the UAV. Using the classicalmethod, the longitudinal pitch angle, altitude and speed controller are designed for separate transfer functions according to thelocation curve of the roots and the desired response values. PID values were determined by considering the response of the systemusing classical methods. On the other hand, a feedback control system has been designed to improve the stability of different lines.And also an orientation controller has been designed. New approach proposed in the study is Adaptive Network Based FuzzyInference Systems (ANFIS) controller. In this study, a new controller approach based on fuzzy logic is proposed. Four data sets, PIDcontrol inputs and control sign have been obtained for the design of the proposed controller. These data sets have been used fortraining the fuzzy controller. As a result; It is presented with graphs that the proposed method is applicable and gives successfulresults.
