Title:
SIX FREEDOM DEGREE CONTROL DEVICE FOR SPACECRAFT
Document Type and Number:
Japanese Patent JP3391292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a six freedom degree control device for a spacecraft which can realize a high accuracy of position and attitude control, and the suppression of the fuel consumption amount.
SOLUTION: A control axis selector 2 selects the shaft direction necessary to control, depending on the position deflection/speed deflection or the attitude deflection/angular speed deflection of a spacecraft 5, and puts out a control axis deflection signal 20 only in this axial direction. A control output calculator 3 calculates an axial control signal 21 only in the axial direction judged to execute a thruster control depending on the above signal 20. A control axis order deciding unit 4 decides the control order of the axial directions depending on the priority set beforehand to the axes, and the signal 20, and puts out it as a thruster control signal 22 in the order that an axial control signal 21 of an axial unit is decided.
