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。
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。
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。
As an important part of the project of developing an ecs for mw wtgs , the thesis makes overall theoretic analyses and experimental studies on reactive power compensate control system and yaw control system 作为单机电气控制技术研究的重要组成部分，本文对无功补偿控制系统和偏航控制系统展开了比较全面的理论分析和实验研究。
The control system faces the wind actively by logical control and is controllable during the process of facing wind . it can exactly trace wind direction and automatically release winding cable caused by the yaw 该系统采取逻辑控制主动对风，实现了对风过程可控，准确跟踪风向并能自动解除由于偏航作用引起的电缆缠绕等功能。
The paper designed aerodynamic control system of pith and yaw channels and roll angle stabilization system , by using unsteady - state error follow - up control theory and state observation station theory in modern control theory 本文使用现代控制理论中的无静差跟踪控制系统理论与状态观测器理论，设计了俯仰、偏航两个通道的气动力控制系统和滚转角稳定系统。
Thirdly , by neglecting the coupling influence , the control laws of pitching , yawing and sloping movements are designed separately with frequency domain analysis and root locus , and then the parameters of the controller are chosen 第三，忽略耦合影响，将控制系统分为俯仰、偏航、倾斜三个相互独立的通道，用频域分析法和根轨迹法设计控制律、选取控制器参数。
Chapter 2 exposits the principle of the airborne isar imaging of ship targets in detail using the concept of image projection plan and effective rotating vector . and some imaging results under every ship sway ( roll , pitch and yaw ) are presented 论文第二章借助成像投影面和有效旋转矢量的概念,详细阐述了机载isar对舰船成像的机理,并分别对舰船横摇、纵摇、偏航运动成像进行了仿真。
