Abstract :
A transfer function model was established based on working principle of marine rudder loading system. Aiming at rudder movement signals polluted by noise, a wavelet analysis method was proposed to analyze the characteristics of surplus force. Using multiresolution analysis, actual experiments signals was decomposed. Denoised and reconstructed speed and acceleration signals manifested their real relationships with surplus force. Results of eliminating experiments verified the effectiveness of proposed method.
