  • Patent number: 12187463
    Abstract: A control method for controlling a momentum wheel device for stabilizing a spacecraft includes: providing the momentum wheel device as a real momentum wheel device having a momentum wheel driven by a motor; providing a simulated momentum wheel device based on an ideal physical model; concurrent feeding of a torque command to both momentum wheel devices, to change a rotational speed of both momentum wheel devices; controlling the motor to change the rotational speed dependent on the fed torque command; detecting a real rotation angle of the real momentum wheel device; calculating a simulated rotation angle of the simulated momentum wheel device by two-fold integration of the fed torque command; comparing the real rotation angle and the simulated rotation angle and generating an error signal corresponding to a deviation between the real and simulated rotation angles; and controlling the motor due to the error signal to reduce the deviation.

  • Patent number: 11492144
    Abstract: The invention relates to a flywheel for stabilising the position of a spacecraft, comprising a hub means (1) for fastening the flywheel, a flywheel ring (4), which externally surrounds the hub means (1) circumferentially at a distance, a support means (3) for supporting the flywheel ring (4) on the hub means (1), and a vibration damping device (6, 8) having a tuned mass damper means (8) which is axially movable back and forth relative to the flywheel ring with respect to a rotation axis of the flywheel.

  • Publication number: 20210171222
    Abstract: A control system for a momentum wheel device is specified, wherein the momentum wheel device is a real momentum wheel device (1) and has a momentum wheel which is driven by a motor, and wherein a simulated momentum wheel device (2) is provided which simulates the behaviour of an ideal momentum wheel on the basis of an ideal physical model (12). The rotational speed of both the real momentum wheel device (1) and of the simulated momentum wheel device (2) can be changed by a torque command (6). A comparator device (11) is provided for comparing the real rotational angle (9) of the real momentum wheel device (1) and the simulated rotational angle (14) of the simulated momentum wheel device (2) and for generating a fault signal (15) corresponding to a deviation between the real rotational angle (9) and the simulated rotational angle (14). The fault signal (15) can be conducted to a control device (3), in order to actuate the motor on the basis of the fault signal (15), for the purpose of reducing the deviation.

  • Patent number: 10138004
    Abstract: The invention relates to a flywheel device for position stabilization of a spacecraft, comprising a carrier (1), a rotor (2), a magnetic drive (4) for the rotatingly driving the rotor (2) relative to the carrier (1), and a roller bearing (3) arranged between the rotor (2) and the carrier (1). A magnetic force can be generated between the rotor (2) and the carrier (1) by means of the magnetic drive (4) in order to pre-stress the rolling bearing (3). The outer diameter (A) of the rotor (2) can have, for example, only a maximum of 2.5 times of the rolling bearing diameter (W).

  • Patent number: 6585241
    Abstract: A device for the vibration-absorbing mounting of a compressed-air generator including a first spring element which is mounted on a mounting support. A second spring element is provided on which the compressed-air generator is arranged. One of the two spring elements has a spring rigidity in essentially the vertical direction that is maximally half its spring rigidity in essentially the horizontal direction. The second spring element is arranged in series with the first-spring element. The inventive device reduces the acceleration measured at the bottom of the understructure to values which are at least 30% of the values known from the prior art.
