Design of self balancing pitch control in fixed wing unmanned aerial vehicle with fuzzy logic controller

In UAV flight controller's design, the occurrence of errors due to the delay in the system response to the reference signal from the pilot and the lack of stability in flat conditions due to interference or unbalanced mechanical load. When this happens UAV can not be controlled and the flight conditions can not be maintained any more. Fuzzy controller offers a solution for the development of UAV's stability controllers, specialized in the design of the autopilot system that controls the pitch angle of the UAV. This research has been developing a prototype of fixed wing UAV that can be controlled wirelessly and has ability to maintain the balance on the pitch angle of the flat conditions (self-balancing). Run test results show that the applied fuzzy method succesfully controls the pitch angle to maintain a flat condition the developed UAV
