民用飞机偏航控制系统设计策略

偏航控制系统是保证飞机安全飞行的关键系统,方向舵是偏航控制主要操纵面.针对方向舵主-主-主余度配置,设计其权限管理和故障重构策略;针对偏航阻尼功能闭环控制方式的特点,设计其指令表决及弹性模态之间的不良耦合规避策略;实现一种高安全性和高可靠性的偏航控制系统.

Control Strategy Yaw Control System for Civil Aircraft

The yaw control system is the critical system to ensure the safe flight of aircraft, and therudder is the main surface of the yaw control. Aiming at the rudder surface active-active-active configuration , its authority management and fault re-configuration strategy were designed. In terms of thecharacteristics of the closed-loop control mode of the yaw damper function, its commanding votinglogic and evasion strategy of the elastic mode were designed and a high safety and high reliability ofthe yaw control system.
