Attitude control of flexible communications satellites
Abstract
This paper investigates alternate control techniques for the
attitude control of a three axis stabilized flexible communications
satellite consisting of a large reflector and a solar array. The control
configurations consisted of three classes: Class 1 - sensors and
actuators co-located on the central body, Class 2 - actuator on the
central body and sensors distributed, and Class 3 -actuators and
sensors distributed. Criteria are developed for modal truncation. The
results indicate that Class 2 can cause instability and. is not generally
a desirable design approach. An experimental setup to study the
effects of flexibility on attitude control per-formance during slew
maneuvers and wheel desaturation is also discussed.
