摘　　要：阐述了舰船在机动情况时舵角反馈信号对航向精度的提高以及对横漂速度的估计作用,结合舰船的运动模型和航向角H与舵角β的关系模型,考虑横漂速度对舰位的影响,引入舵角反馈信息,建立了有舵角反馈信息参与的kal-man滤波模型,并利用Matlab软件将有/无舵角信息参与的kalman滤波模型进行了比较,结果显示有舵角信息参与的kal-man滤波模型效果较好。Expounding rudder feedback signal＇s effect for improving course precision and estimating sawy velocity under the condition of ship＇s maneuver movement. Combining ship movement＇s model and the relation between heading H and rudder angle β , considering the impact of sawy velocity on ship＇s positioning, inducting rudder feedback signal into the filter model, establishing kalman filter model which is concerned with rudder feedback signal. Utilizing the software of Mattab to compare the kalman filter model with rudder feedback signal with the kalman filter model without rudder feedback signal, and the filter with rudder feedback signal has a better effect.
