Real-time computation of time-optimal magnetic attitude control Conference Paper uri icon


  • Magnetic actuators have been used for momentum dumping and attitude control in many spacecraft. Of late, magnetic actuators have also been proposed as a sole means for attitude control, particularly for small inexpensive spacecraft. In this paper, we investigate the use of magnetic actuators for the time-optimal slew maneuver using a spectral algorithm implemented in the reusable software package, DIDO. The parameters of the example problem correspond to that of NPSATI, a small satellite being built at the Naval Postgraduate School, and due to launch in January 2006. Numerical experiments reveal that real-time optimal solutions can be easily obtained.
