A rapid and stable rest-to-rest manoeuvre-scheme is developed for a spacecraft which needs a quick attitude reorientation. By using this scheme, a minimum-time manoeuvre is realized under the limit of sensor's and actuator's capability. In this schem

The Institute of Space and Astronautical Science report. 680:1-51
For the high-accuracy attitude control of spacecraft, Magnetic Bearing MomentumWheel (MBMW) has been being investigated as an actuator because of its merits of low disturbancecharacteristics and "gimballability" when a suitable active controller is u

As pointing requirements of astronomy satellites become more demanding, a conventional momentum-exchange scheme for attitude-pointing control is sometimes not enough to satisfy stringent stability requirements. This paper presents a new attitude cont
