摘要：ABSTRACT: This paper presents the controlling of model of a four rotor vertical take-off and landing (VTOL) unmanned air vehicle known as the quad-rotor aircraft. The paper presents two controlling methods for the flight control of an autonomous quad rotor. The dynamic model of the quad-rotor, which is an under actuated aircraft with fixed four pitch angle rotors, will be described. The controlling of a quad rotor vehicle is not an easy task because of its complex structure. The aim is to develop a control of the vehicle is easy. This paper explains the developments of a PID (proportional integral-derivative) control method and fuzzy logic control method to obtain stability in flying the Quadrotor flying object. In model there four input forces which are basically the thrust provided by each propeller connected to each rotor with fixed angle. Forward (backward) motion is going to maintain by increasing (decreasing) speed of front (rear) rotor speed while decreasing (increasing) rear (front) rotor speed simultaneously. The aim of this paper is to give enhance performance of quad-rotor.
