摘　　要：为了研究船舶运动状态下的风速风向精确测量,设计了一种船舶风速风向动态测量及误差补偿的数字仿真系统;通过对船舶航行状态下的风速风向测量原理进行分析,建立了船舶平面运动的相对风速风向和真风风速风向的解算模型,并根据船舶空间运动的风速风向测量及其误差补偿算法,对船舶横摇、纵摇状态下的风速风向的动态测量和误差补偿进行了数字仿真;数字仿真结果表明,该方法能够消除船舶航行时的运动姿态对风速风向测量带来的影响,为船舶的操纵控制和航行安全提供了精确和可靠的风速风向数据信息。In order to research the precise measurement of the wind speed and direction with ships motion, a digital simulation system of dynamic compensation and error compensation for wind speed and direction is designed. According to the measurement principle of wind speed and direction with ship plane motions, the solution model of relative wind and true wind with ship plane motions is established. Meanwhile, according to the error compensation algorithm for wind speed and direction measurement with ship spatial motions, Dynamic measurement and error compensation for wind speed and direction with ship roiling and pitching state is simulated. Digital simulation results show that effects on measurement of wind speed and direction with ships motion is eliminated, the accurate and reliable data information of wind speed and direction is provided for manipulation control and navigation safety for ships.
