    摘要： A method for determining a maneuvering reserve in an aircraft having a number of propulsion units, preferably a multirotor VTOL aircraft, most preferably an aircraft with electrically operated drive units for the rotors, including the steps: a) Determining a control vector, τ, for the aircraft, τ=(L M N F)T, the components of which represent control torques of the aircraft around the roll axis, L, the pitch axis, M, and the yaw axis, N, and a total thrust, F, b) Approximating an existing four-dimensional control volume, D, of the aircraft by a four-dimensional ellipsoid, E, the axes of which represent the control torques, L, M, N, of the aircraft and the total thrust, F, c) Determining a normalized control vector, τind=(Lind Mind Nind Find)T for the aircraft, using axis dimensions, Lmax, Mmax, Nmax, Fmax, of the ellipsoid, in particular semi-axis dimensions of the ellipsoid; and d) Outputting at least the normalized control vector, τind, for determining a permissible flight maneuver in at least one dimension of the four-dimensional control volume.

    摘要： The present invention relates to a control method for a control apparatus for an aircraft, the control apparatus including a communication unit and a processor. The control method includes receiving an address of a delivery location to which a delivery product is to be delivered, and controlling an aircraft by means of the communication unit to deliver the delivery product to the delivery location, in which the controlling of the aircraft by means of the communication unit includes selecting, on the basis of the address, any one of a plurality of delivery criteria that defines an area into which the aircraft is to unload the delivery product, establishing a delivery area and a flight lane to the delivery area on the basis of the delivery criterion, controlling the aircraft to allow the aircraft to fly along the flight lane, and controlling the aircraft to unload the delivery product into the delivery area when the aircraft reaches the delivery area.

    摘要： A method controls a drone along a shaft having adjoining first and second shaft walls. A drone sensor system detects an environment and/or a state of flight, an actuator system controls the drone, and a control device controls the actuator system. Method steps include: control device receiving sensor data generated by sensor system; determining actual distances of drone relative to first and second shaft walls from sensor data; and generating control signal actuating actuator system such that drone flies based on deviation of actual distances from target distances and a target flight route to a target position. An actual flight route is determined from the sensor data, and the control signal is generated based on a deviation of the actual flight route from the target flight route. Door regions and/or height markings in the shaft are recognized from the sensor data to determine the actual flight route.

    摘要： A method of controlling a transition aircraft having actuators and which transitions between a first take-off/landing regime and a second horizontal flight regime, including: controlling a first actuator subset in the first regime and a second actuator subset in the second regime using the flight controller, by: a) providing measurements or estimates of flight parameters; b) depending on a current regime, checking whether a predefined set of conditions for that regime are fulfilled, by comparing flight parameters with threshold values; c) if conditions are fulfilled, signalling a decision-maker and awaiting confirmation regarding a transition to the other regime; d) instructing the flight controller to make the transition if approved; e) after transitioning in step d), commanding the aircraft according to the other regime; and f) returning to step a). Step e) includes gradually blending in a control law for the other regime over time while blending out the current regime.
