To provide ram line control device and method by which an attitude of a flying object during spinning can be controlled with high accuracy even if control delay greatly fluctuates.SOLUTION: A ram line control device 100 comprises a gas injection device 9, an inertia measurement device 20, and an attitude control device 30. The inertia measurement device 20 outputs an attitude ratio of pitch, yaw and roll of a flying object 1 and an attitude angle of the pitch, yaw and roll. The attitude control device 30 outputs an injection command signal A to the gas injection device 9. The attitude control device 30 has an actual roll angle calculator 32, a correction roll angle calculator 33, a main roll angle calculator 36, and an injection controller 37. The correction roll angle calculator 33 calculates a yaw attitude error angle ΔLy and a pitch attitude error angle ΔLz with respect to a target attitude 3, and calculates a correction roll angle θc for injection of a gas jet 4 on the basis of them. The main roll angle calculator 36 corrects a target roll angle θx for injection of the gas jet 4 on the basis of the correction roll angle θc.SELECTED DRAWING: Figure 4 【課題】制御遅れの変動が大きい場合でも、スピン中の飛翔体を高精度に姿勢制御できるラムライン制御装置と方法を提供する。【解決手段】ラムライン制御装置１００が、ガス噴射装置９、慣性計測装置２０、及び姿勢制御装置３０を備える。慣性計測装置２０は、飛翔体１のピッチ、ヨー、ロールの姿勢レート及びピッチ、ヨー、ロールの姿勢角を出力する。姿勢制御装置３０は、ガス噴射装置９に対する噴射指令信号Ａを出力する。姿勢制御装置３０は、実ロール角演算器３２、補正ロール角演算器３３、主ロール角演算器３６、及び噴射制御器３７を有する。補正ロール角演算器３３は、目標姿勢３に対するヨー姿勢誤差角ΔＬｙ及びピッチ姿勢誤差角ΔＬｚと、これらに基づきガスジェット４を噴射する補正ロール角θｃを演算する。主ロール角演算器３６は、補正ロール角θｃに基づき、ガスジェット４を噴射する目標ロール角θｘを修正する。【選択図】図４
