The switch logic between high thrust and low thrust , switch rule between ppc methed and qsc methed , and the switch maneuver between pitching and attacking in af are given 给出了高水平推力和低水平推力的切换逻辑，相平面控制与准滑模控制律的切换准则和角度反馈中俯仰角和攻角的切换策略。
The antenna ' s model was dynamically compensated with the extended state observers and it was simplified to two approximately decoupled integrator systems in the azimuth and elevation channels 采用扩张状态观测器对天线模型实现动态补偿，则在方位和俯仰通道上被简化为两个近似解耦的积分系统。
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。
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。
And then two deep - stall recovery control laws are designed : pitch oscillation control law based on the lyapunov method and slide modeling anti - control law based on the slide modeling anti - control technique 然后分别用李雅普诺夫方法和滑模反控制方法设计了两种深失速改出控制律，即俯仰振荡控制律与滑模反控制律。
Image movement that is brought by aeroplane movement ( including the forward movement , pitching and yawing movement ) will be eliminated , and then image quality of camera will be improved after the research 通过本文的研究，消除机载平台产生的像移(指飞机前向飞行和俯仰偏航运动引起的像移误差) ，提高相机成像质量。
The coordinate transformation technology is adopted to compensate real time attitude angles of the swinging ship on the azimuth and pitching axis of tracking equipment in order to stabilize los and improve precision 故采用坐标变换技术，在跟踪设备的方位和俯仰轴上对船摇姿态角进行实时补偿，达到视轴稳定、提高精度的目的。
Firstly , the four features of five air targets are extracted here : target identity ( tid ) , elevation measurement , target speed and acceleration . then the statistical models of features are established to classify five air targets 首先，就五类空中目标提取了四种特征：目标身份、俯仰角、速度和加速度等，同时建立了它们的统计模型。
Their weights vary with the velocity of the platform and the requirements of the precision and the data - rate of the ins or gps are very high at the beginning the distribution of the space - time spectrum of the clutter is studied 一方面，主瓣杂波的带宽和斜率随着扫描方位角的变化而变化；另一方面杂波的二维分布随着距离或俯仰角的变化而变化。
Searching satellite is to change the azimuth angle and pitching angle by making antenna circumrotate azimuth axis and pitching axis with controller , so antenna can point itself to different satellite according to the demands 寻星就是通过控制器的控制使天线围绕方位轴和俯仰轴旋转，从而改变天线的方位角和俯仰角，使天线根据要求对准不同的卫星。
