摘要
建立了船舶横向运动状态方程和测量方程,利用扩展卡尔曼滤波方法对海浪扰动下的船舶横向运动的扰动力和力矩作出估计。仿真结果表明,扩展卡尔曼滤波法比有色卡尔曼滤波法估计效果更优。
Sets up the horizontal motion state equation and measure equation of shipping,using extended Kalman filter, estimates the disturbed force and moment of shipping's horizontal motion in disturbed ocean wave. Simulation results indicate that extended Kalman filter is better than colored Kalman filter.
