报告摘要

This lecture describes the existing technologies and problem of saturation in attitude control devices for spacecraft such as satellites. Three main devices are presented: reaction wheels, control moment gyroscopes, and a new proposed device under development called the spherical levitated actuator. The mathematical models of all three devices are presented and simulations are used to illustrate the momentum saturation problem in attitude control of spacecraft.
