Abstract:
1. A method for controlling an unmanned remote controlled airborne object capable of hovering comprising the steps of: generating a steering signal formed by a pilot using a pickup unit and wherein for achieving at least in part an automatic restoring of the horizontal attitude of the airborne object when the pickup unit is neutralized; generating at least one rotation signal of an angular rate of at least one of an inclination pitch (elevator) and roll is formed, the at least one rotation signal is integrated with respect to time using an integrator, and the integral is being drawn upon, within the scope of a closed-loop-control, as an actual value of an angle of inclination, and a steering signal is being drawn upon as a nominal value of an inclination angle, and the difference between the actual value and the nominal value is transferred to an actuator unit controlling the flight attitude, and wherein the duration of the integration time is narrowed down accordant to a defined time constant or accordant to a defined time window.
