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, a wheel driver that transmits a wheel drive signal proportional to the change in attitude signal to the flywheel, and rotation of the flywheel. a detector that detects the number of rotations and transmits a rotation speed signal proportional to the rotation speed to the controller; a controller that outputs a magnetic coil control signal proportional to the rotation speed signal to the magnetic coil; satellite dynamics for subtracting a control torque generated by interfering the generated magnetism generated by the magnetic coil with the earth's magnetism from the disturbance torque to output it as an input torque and transmitting the input torque to the flywheel; A comparator that outputs an abnormal signal in response only to the rotation speed signal corresponding to when the rotation speed of the satellite reaches saturation, and an amplifier that outputs a magnetic coil control auxiliary signal in proportion to the abnormal signal are installed simultaneously on the artificial satellite. The attitude of the satellite is controlled by inputting the magnetic coil control auxiliary signal to the magnetic coil together with the magnetic coil control signal and driving the magnetic coil.
A magnetic attitude control device for an artificial satellite, which controls the satellite so that a certain side always faces the earth.
