| Abstract: | The principle of measurement and nonlinearity of lift force were analyzed based on the lift fin stabilizer system,and fin-lift/fin-angle integrated control method was adopted in the servo system of fin stabilizers with lift force feedback control,which could modify the lift force feedback detection signal.The data fusion model was built based on wavelet denoising algorithm,the different bandwidth information from the lift force and fin angle sensors were integrated to smooth out the redundancy and contradic... |
