Because there are no horizontal fluid restoring forces in ship motion , the responses such as sway and yaw in time domain will not converge to a stable state 由于船舶在水平面内没有恢复力(矩) ，导致时域计算中水平面内的船舶运动发散。
Weapons should not need to use 3 degrees of rotation ( pitch + yaw + roll ) . if you really need such a config , please contact a developer first 武器应该不需要3个旋转轴（俯仰自旋翻转） 。如果你确定需要这样的构造，请先联系开发人员。
With the increase of the relative velocity , the variations of side force coefficient and yawing moment coefficient of the overtaken vehicle will increase linearly 被超车侧向力系数和横摆力矩系数的变化量随两车相对车速的增加呈线性增加的趋势。
The study object in this paper is a lunate caudal fin imitating tuna - tail with the mode combined swaying and yawing in uniform flow which is incompressible and inviscid 本文的研究对象是类似于金枪鱼尾鳍的一个推进装置，它是一个月牙形的尾鳍。
This auv are designed to have three thrusters , two horizontal thrusters are used to surge and yaw , one vertical thruster is used to heave 这里，水下机器人具有三个推进器，两个水平推进器用来完成推进和转首动作，一个垂直推进器用来完成升沉动作。
On the basis of analyzing the control process completely , the thesis designs yaw control system for wtgs using 89c51 single - chip computer as a main control unit 在详细分析偏航控制系统控制要求的基础上，采用单片机89c51作为主控单元，设计了风电机组的偏航控制系统。
The spin , sometimes called the negative spin , occurs when the angle of attack of the canopy is increased and one side is stalled causing it to drop almost vertically and spin on its yaw axis 旋转，有时候叫反向旋转，发生于当伞的攻角增加，而且单侧失速时，引起几乎垂直地下坠，同时绕著它的偏移轴心旋转。
3 . the combined trajectory control system is designed . the direct force is acting on the pitch channel and the yaw channel , and the roll channel is stabilized by the fin surface deflection 设计的轨控直接力作用于俯仰和偏航通道，而滚转通道没有直接力系统的作用，依靠气动舵面的偏转对滚转角进行稳定。
Active yaw control , first incorporated into the evo iv , was developed by mitsubishi to improve a vehicle ' s cornering and acceleration performance , and consequently its safety , under a wide range of operating conditions 主要结构是装在后轮半轴间的湿式多版差速器，最里面的一组减速齿轮调节左右轮驱动力分布。
So , variable structure control theory is used in angle stabilization of roll , and model - following variable structure control theory is used in acceleration stabilization of pitch and yaw 因此，本文采用了变结构控制理论设计倾斜角稳定系统，采用了模型跟踪变结构控制理论设计俯仰、偏航通道的加速度稳定回路。
