Abstract EN
Due to the lack of true ship angular flexure data, it is difficult to evaluate its measurement error of the angular velocity matching method in practice.
In this paper, the cause of the measurement error of the ship flexure angle is analyzed in theory, and an evaluation method for the ship angular flexure measurement error based on the principle of relevance is proposed.
The proposed method provides a prediction formula to describe the estimation error of the static flexure angle based on the off-diagonal elements of the error covariance matrix P in Kalman filtering.
In addition, the optimized coefficient F is introduced to make the prediction error range better describe the real error variation.
The optimized coefficient F ensures that the proposed formula has good prediction effects in all three directions.
Simulations based on the actual measured ship flexure data are carried out, and the simulation results verify the capability of the prediction formula.
The proposed method can be used in the evaluation of the ship flexure measurement error.
