Analysis, Design, and Implementation of an Autopilot for Unmanned Aircraft - UAV´s Based on Fuzzy Logic

The UAV (Unmanned Aerial Vehicles) they have demonstrated their enormous capabilities in military and civilian applications in recent years. They have become an indispensable tool in the field of defense, security and support for the development of a nation. Similarly, the technological development has allowed these aircraft to fly autonomously thanks to electronic control systems called autopilots. The functional architecture of the autopilot which has been presented in this paper bases its operation on fuzzy logic for complete control of the aircraft, in stability, altitude, course, direction and acceleration using the minimum possible controls, reducing the computational processing. The system presented is tested through multiple flight hours in different climatic conditions, the results are satisfactory and the system shows to be really promising. Both the hardware and software of the proposed control system are the result of teamwork of Ecuadorian researchers.
