Outline of Final Research Achievements

We developed an attitude control system for a small telescope in order to make in-situ observations of the rotation of the Moon and the planets. A tube with a sharp bottom end is put on an XY linear translation stage and the top is surrounded by a ring with 4 pressure gauges inside. It is a kind of an inverted pendulum and it is kept vertical by adjusting the position of the bottom end. We made experiments with a device composed of an inverted pendulum suspended by two springs which can move only in one direction and have succeeded in keeping it vertical with the accuracy of better than 1 arc sec. The accuracy is improved by using weaker springs and it is possible to control with the accuracy of 1 milli arc sec.

Academic Significance and Societal Importance of the Research Achievements

鉛直または水平の基準は、測地学や位置天文学の科学的な観測にとって重要であるばかりでなく、測量や精密加工等の実用的な必要性も高く、基本的、かつ、応用範囲が広い課題である。倒立振子の制御については、二足歩行ロボットの関係で制御工学の分野で多くの研究があるが、望遠鏡の姿勢制御に応用しようとする研究は初めてであり、望遠鏡の姿勢制御の方式として新しい展開が期待できる。また、鉛直を基準にしている多くの日常的な機器の高精度化への新しい展開も期待できる。今回開発した方式の利点は、液体を用いないこと、より高感度であることである。
