Attitude control device, spacecraft, attitude control method, and attitude control program

摘要

PROBLEM TO BE SOLVED: To control attitudes simultaneously in three axes using a small number of control moment gyros.SOLUTION: Two control moment gyros 13 of an attitude control device 10 individually have a wheel 31 and a gimbals 32. A gyro calculation unit 24 of the attitude control device 10 calculates a command value for each of the control moment gyros 13 as for an angular speed of the gimbals from a set value of a torque in a three-axes direction for controlling the attitude. The gyro calculation unit 24 calculates a common change amount for an angular momentum of a wheel from a set value of a torque in a three-axes direction for controlling the attitude, then weighs the calculated common change amount with a coefficient for each of the control moment gyros 13, and calculates a command value for each of the control moment gyros 13.SELECTED DRAWING: Figure 1
