UARMS has been developed for radiation monitoring around Fukushima Dai-ichi nuclear power plant which spread radiation contaminant due to the huge tsunamis caused by the Great East Japan Earthquake. The monitoring area contains flat as well as mountain areas. The basic flight controller has been confirmed to have satisfactory performance with respect to altitude holding; however, the control performance for variable altitude commands is not sufficient for practical use in mountain areas. We therefore design preview altitude controller with only proportional gains by considering the practicality and the strong requirement of safety for UARMS. Control performance of the designed preview controller was evaluated by flight tests conducted around Fukushima Sky Park., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: DS1740004003}, pages = {54(14)--63(23)}, title = {放射線モニタリング無人固定翼機の予見制御による高度制御性能向上}, volume = {65}, year = {2017} }
