| description | This paper describes a comparison study of magnetic attitude control
torque generation performance of a momentum bias satellite operated in
Low Earth Orbit (LEO) with various orbit inclinations. The satellite is
equipped with two magnetic torquers that are placed along the +x and +y
axes where magnetic control torque is generated when these magnetic
torquers couple with the geomagnetic fields and its vector direction is
perpendicular to both the magnetic fields. The control algorithm was
structured using a proportional (P) controller for satellite attitudes/nutation
control and a proportional-integral (PI) controller for managing the excess
angular momentum on the momentum wheel. The structured control
algorithm is simulated for 23°, 53° and 83° orbit inclinations and the
generated attitude torque performances are compared to see how the
variation of the satellite orbit affects the satellite’s attitude torque generation
as the magnitude and direction of the geomagnetic fields vary with respect
to the altitude and latitude while the magnitude and direction of the
magnetic fields generated by the magnetic torquers vary with respect to
the orbital motion. Results from simulation show that the higher orbit
inclination generates optimum magnetic attitude control torque. Note that
this work is the extension of the previous work published in The
International Journal of Multiphysics [1]. |
