초록

In order to control an attitude of a movable object having a flexible member (50) through an attitude maneuver, first, based on vibration of the flexible member at the time of the attitude maneuver, for example, a sampling function including no frequency components equal to or higher than a particular frequency is obtained. With the use of the sampling function, a control target value is created as a previously-frequency-shaping-type feedforward control law. Based on the control target value, attitude control data is created. The attitude control data ca...

1. An attitude control data creating method of creating attitude control data for an attitude maneuver with respect to an artificial satellite having a flexible member, comprising: a sampling function obtaining step of obtaining, based on vibration of the flexible member at a time of the attitude maneuver, a sampling function excluding frequency components equal to or higher than a particular frequency, the sampling function being a sinc function capable of creating a waveform of an attitude profile in which frequency components are completely separated;...
