艏摇 meaning in Chinese

yawing

Sea wave high , pitching force , rolling force and rearing torque simulation algorithms are put forward
给出了随机海浪波高、横荡力、横摇力矩、艏摇力矩的仿真算法。
Because of the change of ship attitude ( rolling angle r , pitch angle p and course angle h ) led by ship rocked interference and windage , the los stabilization will be influenced obviously
由于舰船的艏摇、纵摇、横摇等引起舰船姿态的变化以及风阻力矩的作用，对跟踪系统的视轴稳定性产生明显影响。
The author choosed weighting matrix for different sea conditions , designed the controller and the rudder / fin joint control system . finally , the author simulated the controller with matlab . according to the simulation curves and data , we could find that the controller designed using state feedback control theory has nice control performance on rearing and rolling , but the control performance on pitching is not very good
为不同的海情选取了加权阵，求出控制器，完成了船舶舵鳍联合控制系统的设计工作最后，用matlab语言对控制器进行仿真，从仿真曲线和仿真数据可以看出，使用状态反馈h ~控制理论设计出来的控制器对艏摇与横摇有较好的控制效果，而对横荡控制效果不理想，基本达到控制目的。
