摘要
为增强飞机高空、高速飞行时的侧向稳定性,基于自动控制反馈原理,将飞机侧向角速率作为反馈信号,与飞机自身形成飞机荷兰滚阻尼器系统,以提高飞机侧向运动的阻尼。在对飞机侧向阻尼器工作原理简要介绍后,建立其原理结构图,分析和设计其系统控制规律,进行大量对比仿真。仿真结果显示,飞机侧向阻尼器结构简单,在其控制规律传动比等参数选择合理时,飞机侧向阻尼器系统品质良好。
In order to improve aero Lateral fight stability in high altitude and velocity,according to auto feedback principle,the aero yawdamper with airplane itself and its yawangle speed feedback signal was formed,so as to increase aero lateral motions damp.After aero yawdamper work principle was briefly intro duced,its principle structure diagram was established,and its control law was analyzed and designed.A great deal of contrastive simulation has been done under the MATLAB platform.The simulation result shows：the aero lateral damper structure was simple and reasonable,and easy to realize.When its control law ratio was reasonable,the designed aero damp control system can improve aero fight quality.
