姿勢制御装置。 When a disturbance torque acts on an artificial satellite and the certain side of the artificial satellite changes so that it no longer faces the earth,
An attitude sensor that detects changes in the satellite's attitude and outputs an attitude signal proportional to the change in attitude, and a rotating wheel driver that transmits a rotating wheel drive signal proportional to the change in attitude signal to the magnetically supported rotating wheel. , a detector that detects the rotation speed of the magnetically supported rotating wheel and transmits a rotation speed signal proportional to the rotation speed to the controller, and a ground station that generates a torque command to cancel the rotation speed signal and disturbance torque. A controller that compares the magnitude of magnetic control commands and outputs a magnetic coil control signal proportional to the difference between the two signals to the magnetic coil, and a controller that outputs the generated magnetism generated by the magnetic coil in proportion to the magnetic coil control signal to the earth's magnetism. By subtracting the control torque caused by the action from the disturbance torque,
It is equipped with satellite dynamics that transmits input torque to the magnetically supported rotating wheel, and controls the angular momentum of the magnetically supported rotating wheel by applying input torque to the magnetically supported rotating wheel. A magnetic attitude control device for an artificial satellite, which controls the attitude of the satellite so that a certain side of the satellite always faces the earth.
