重力傾度安定方式を用いた人工衛星の構造系と制御系の同時最適設計

摘要

近年，小型衛星の開発が活発に行われている．本学におrnいても「SOHLA-1」を設計し，主衛星である地球温暖化rnガス観測衛星GOSAT（いぶき）の副衛星として2009年1rn月23日にJAXA種子島宇宙センターより打ち上げられた．%In general, small satellites must achieve relatively high performance in spite of their restricted resources. To contribute such developments of small satellites, in this paper, we propose a new method of attitude controller synthesis of small satellites. This method is developed by a strategic use of gain-scheduled controller synthesis from the viewpoint of simultaneous optimization of structural and control systems. It also includes some modification of the existing gain-scheduled controller synthesis to achieve fixed closed-loop property. A numerical example of a gravity-gradient stabilized satellite illustrates the effectiveness of the proposed method in a practical application.
