The aim of this study is to design an autopilot system for Unmanned Aerial Vehicle (UAV) in a small size and to compare the efficiency of the systems designed with different methods. For this purpose, linearized equations of motion for a small size UAV is firstly obtained. Then the state space equations are used to check the stability characteristics of the UAV. Using the classical method, the longitudinal pitch angle, altitude and speed controller are designed for separate transfer functions according to the location curve of the roots and the desired response values. The values were determined by considering the effects of P, I and D and the response of the system together. On the other hand, a feedback design has been designed to improve the stability of different lines and an orientation controller has been designed. Another method used was Adaptive Network Based Fuzzy Inference Systems (ANFIS) controller design. The value ranges and numbers of the input and output functions are tried to be determined by some predicted and known values. Arrangements for input and output coefficients were made and the results were tried to be improved.
