飞翼布局飞行器副翼性能及重构分析

针对飞翼布局飞行器副翼在偏转过程中引起的纵横航向运动耦合的问题,应用升降舵、副翼和阻力舵协调偏转的方法进行控制.为提高飞翼飞行器的生存性,对舵面故障时的重构方法进行了研究.升降舵故障时,直接应用伪逆法即可应用副翼完成重构;阻力舵故障时,为解决伪逆法带来的系统不稳定及重构后系统稳态精度差的问题,将一种基于劳斯稳定判据的、加入了比例-积分控制器的改进伪逆法引入重构.仿真结果表明:该方法在保证系统稳定的基础上能够使系统性能得到最大程度的恢复.

Aileron control and reconfiguration of flying wing aircraft

To decouple the longitudinal and lateral-directional coupled motion caused by the aileron deflection of the flying wing aircraft,the elevator and the split-drag-rudder(SDR) were used to cooperate with the aileron to decouple the coupled motion.In order to increase the flying wing aircraft survivability,the reconfigurable control system had been investigated.In the elevator failure reconfiguration,the pseudo-inverse method was directly used to reconstruct the control system by the aileron.In the SDR jamming ...
