To stabilize ship speed when changing the blade angle of a controllable pitch propeller.SOLUTION: A ship propulsion system 100 comprises a main engine 3 to generate driving force, a controllable pitch propeller 4 rotated by the driving force of the main engine 3, and a control device 6 to control the rotating speed of the main engine 3 and the blade angle of the controllable pitch propeller 4. The control part 6 has an estimation part to estimate an estimation value of the propulsion output of the controllable pitch propeller 4 based on the rotating speed and the blade angle, and an operation control part to control the rotating speed and the blade angle so that the estimation value keeps constant during changing the blade angle when changing the blade angle.SELECTED DRAWING: Figure 1

    【課題】可変ピッチプロペラの翼角を変更する際の船速を安定化させる。【解決手段】船舶推進システム100は、駆動力を発生する主機3と、主機3の駆動力によって回転する可変ピッチプロペラ4と、主機3の回転速度及び可変ピッチプロペラ4の翼角を制御する制御装置6とを備えている。制御装置6は、回転速度及び翼角に基づいて可変ピッチプロペラ4の推進出力の推定値を推定する推定部と、翼角を変更する際に、翼角の変更中の推定値が一定になるように回転速度及び翼角を制御する運転制御部とを有する。【選択図】図1
