| 摘 要： | 基于递推最小二乘法设计并实现海浪干扰力和干扰力矩的成型波滤器,对有色的次优卡尔曼滤波和扩展卡尔曼滤波(EKF)的效果进行对比.通过引入成型滤波器,采用EKF,提高了状态估计的精度,实现对随机海浪扰动力和力矩的估计.仿真结果表明,通过扩展卡尔曼滤波对海浪扰动力和力矩进行估计是可行的.

| Abstract: | The forming filter of stochastic sea interference is designed and realized based on the method of least squares step by step in this paper. The effect of colored Kalman filtering is compared with extended Kalman filtering (EKF). By using the forming filter and EKF, the precision of states estimation is increased and a effective estimation of stochastic sea interference is performed. Simulation result shows that the estimation of stochastic sea interference obtained by EKF is feasible. |
