GIMBAL PROFILE GENERATION DEVICE, GIMBAL PROFILE GENERATION PROGRAM, AND GIMBAL PROFILE GENERATION METHOD

摘要

To provide a gimbal profile generation device which provide gimbal profile generation ensuring convergence without using high-load calculation method for numerically obtaining a convergence direction such as the Newton method.SOLUTION: In a gimbal profile generation device 100, a posture rate calculator 91 calculates a posture rate based on the amount of posture change of a spacecraft. An inverse kinematics calculation unit 95 calculates the first angular momentum of the spacecraft using the calculated posture rate, and second angular momentum of the spacecraft based on a gimbal rotation angle obtained from a gimbal steady state indicating a state in which the three-axis total angular momentum of all CMGs in the coast section is zero and an angular momentum envelope of CMGs. The inverse kinematics calculation unit 95 calculates an initial value of an intermediate gimbal rotation angle based on a gimbal rotation angle change obtained by multiplying a difference between the first angular momentum and the second angular momentum by a matrix that converts an angular momentum time derivative into a gimbal rotation angular velocity.SELECTED DRAWING: Figure 10
