MOMENT GYROS'CLUSTER FOR SPACECRAFT THREE AXIS ATTITUDE CONTROL

摘要

A moment gyro cluster for three axis attitude control of an artificial satellite is provided to improve torque performance by using an MPP(Moore-Penrose Pseudoinverse) driving law. A moment gyro cluster is mounted with a predetermined rotation angle(sigma) between 0° and 360°. Sequential torque inputs are applied as much as rotation amounts of an artificial satellite along an axis direction using a new pyramid shape which the moment gyro cluster is mounted with the predetermined rotation angle. Torque inputs corresponding to x, y, and z axes are sequentially applied in accordance with an artificial satellite attitude movement range in respective axes such that an artificial satellite attitude movement is performed.
