To control propulsive power of a thruster with accuracy.SOLUTION: A thruster controller comprises an opening estimation unit 61 and an opening control unit 62. The opening estimation unit 61 is configured to, based on the balance between acting force applied to a valve body 32 provided in a valve 31 for adjusting an amount of combustion gas injected from a thruster 1 and fluid force 41 applied to the valve body 32 from injected combustion gas, estimate estimated opening of the valve 31 that indicates a rate at which the valve 31 is opened. The opening control unit 62 is configured to, based on the estimated opening, determine control opening for controlling the opening of the valve 31.SELECTED DRAWING: Figure 5
【課題】精度よくスラスタの推進力を制御する。【解決手段】スラスタ制御装置は、開度推定部61と、開度制御部62とを備える。開度推定部61は、スラスタ1から噴出される燃焼ガスの量を調整する弁31に設けられた弁体32に加える作用力と、噴出される燃焼ガスから弁体32に加えられる流体力41とのバランスに基づき、弁31が開かれている割合を示す弁31の推定開度を推定する。開度制御部62は、推定開度に基づき、弁31の開度を制御するための制御開度を決定する。【選択図】図5
