Magnetic Stabilization of Nadir-Pointing Small Satellites

<p>Since magnetic control systems are relatively lightweight, require low power and are inexpensive, they are attractive for small, inexpensive satellites in low Earth orbits. In this thesis we present averaging-based feedback control laws that achieve three-axis stabilized nadir-pointing attitude. Two types of nonlinear feedback control laws are proposed: full-state feedback and passivity-based feedback. Full-state feedback uses the attitude and angular velocity measurements to regulate the spacecrafts dynamics. Passivity-based feedback uses the attitude measurement and doesn’t require the rate sensors. The control laws are tested using two magnetic field models: the tilted dipole model and the International Geomagnetic Reference Field (IGRF) model. Computer simulations are included to illustrate the effectiveness of the proposed control laws.</p>
