ATTITUDE CONTROL DATA GENERATION METHOD AT ATTITUDE MANEUVERING FOR FLEXIBLE STRUCTURE OBJECT AND ATTITUDE CONTROL DEVICE APPLIED WITH THE METHOD

摘要

PPROBLEM TO BE SOLVED: To provide an attitude control device capable of effectively suppressing vibration even if the attitude maneuvering of a flexible structure having a large number of flexible modes is performed and shortening a required time for the attitude maneuvering. PSOLUTION: The attitude control device 40 feeds control signals SBRW/SB, SBCMG/SBto a reaction wheel (RW) of a flexible fluctuation body 50 for an artificial satellite and a control moment gyro (CMG) to attitude-control a body of the artificial satellite. A control target amount profile generation part 6 at attitude maneuvering provided on an attitude induction part 20 of an attitude control circuit 30 obtains a characteristic obtained by calculating the variation of the angular acceleration of the artificial satellite capable of accomplishing attitude maneuvering in the shortest route according to an Euler axis determined before executing the attitude maneuvering based on presumption values of angular velocity SBB/SB, an angle SBB/SBfrom an attitude presumption unit 4. During attitude maneuvering, a control target amount of such a characteristic is generated and fully given to the attitude induction part 20 for executing attitude induction regulation by the control moment gyro and a reaction wheel control part 5 for forming a PID control loop.
