Title:
SPACECRAFT CONTROL DEVICE AND THRUSTER CONTROL METHOD
Document Type and Number:
Japanese Patent JP3390492
Kind Code:
B2
Abstract:
PURPOSE: To provide a spacecraft control device capable of controlling the position and attitude of a spacecraft independently without using its center of gravity, and a thruster control method enabling efficient thruster distribution with a small amount of calculation.
CONSTITUTION: A spacecraft control device is provided with a noninterference computing part 8 for eliminating interference on the dynamics of the operation quantity of position control and attitude control obtained from deviation between the target position value 3 and the output of a position detector 2 and from deviation between the target attitude value 6 and the output of an attitude detector 5, and a feedforward computing part 9 for compensating the acceleration component of the target value and inertial force generated on the dynamics from each target value and the output of each detector. Offset-permutation jet logic utilizing pattern matching is applied in a thruster selecting rule so as to obtain the jet distribution of a thruster small in the total jet quantity.
