Disclosed are a ship having a plurality of propellers and a thrust distributing method thereof, wherein the ship having the plurality of propellers includes: a plurality of propellers installed at different positions from each other to propel the ship; and a control part having a controller in which a target position is input and which measures a difference between the target position and a present position to calculate a final value of required force and required moments and a thrust distributor calculating a rudder angle and thrust of each of the plurality of propellers, wherein the thrust distributor selects a plurality of imaginary values of the thrust and the rudder angle of each of the propellers and selects the value in which an error with the final value is the minimum among combinations of each selected imaginary value as the optimum value. Therefore, the ship having the plurality of propellers enables the optimum thrust distribution without a change into linearization or block functions.

    서로 다른 위치에 설치되어 선박을 추진하는 복수의 추진기; 및 목표 위치가 입력되고, 현재 위치와의 차이를 측정하여 필요 힘과 필요 모멘트의 최종 값을 연산하는 제어기와, 각 상기 복수의 추진의 추력 및 타각을 연산하는 추력분배기로 형성되는 제어부;를 포함하고, 상기 추력분배기는 각 상기 추진기의 타각 및 추력의 복수의 가상 값들을 선정하며, 선정된 각 상기 가상 값들의 조합 중 상기 최종 값과 오차가 최소가 되는 값을 최적 값으로 선택하는 것을 특징으로 하여, 선형화 또는 볼록함수로의 변환 없이 최적의 추력 분배가 가능하도록 하는 복수의 추진기을 구비한 선박 및 그 추력 분배 방법을 개시한다.
