  • Patent number: 8000849
    Abstract: An aid for remotely controlling unmanned aircraft and particular helicopters, which allow the pilot at least approximately to directly stir the angle of inclination, thus for instance a pitch(elevator) and/or roll angle, so that on neutralizing of the steering stick, the respective angle of attitude returns autonomously, and to a large extent goes back to the horizontal position. To this end, a closed-loop control of the inclination is carried out, in that an angular rate signal is being integrated to an actual value, and a nominal value is admixed behind the forming of the integral, wherein the time of integration is shortened in order to avoid null drifts, in particular by feeding a portion of the actual value and/or the nominal value back into the input of the integrator. Furthermore, a vectorial rotation of the integrated actual values by a yaw signal.
