Analysis of real time stabilization effect and parameter optimization of fin stabilizer

The mathematic model of an actually installed fin stabilizer system is developed and simulation model of the system is built using MATLAB/Simulink. The power spectral analysis is performed and the real time stabilizing effect of the fin stabilizer is obtained by calculating the rolling motion of the ship both in conditions that with and without fin stabilizer running. Then, an optimizing platform is developed using iSIGHT software package and optimized control parameter sets are obtained for different operation conditions. At last, DOE analysis is performed to analyze the influence of each control parameter on the stabilizing effect.
