| Outline of Final Research Achievements |
This research addresses the attitude control system of gondolas of the stratospheric balloons which are used for various observations and experiments in the stratosphere. The attitude control system is verified from new point of view where the dynamics includes the suspension and the balloon envelope as well as the gondola, which have been ignored. And the research aims to develope new control strategy for the attitude control method with higher precision and easier system.
This research revealed that the attitude measurement and frequency analysisy of gondolas without attitude controls provide useful information for the development of the future attitude control system.
Also in the research the attitude control strategy is being developed with dynamics parameters which have been deteremined in this research.
