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 failure, an improved pseudo-inverse reconfigurable method based on the routh stability was designed with the proportion-plus-integral (PI) control. The method guaranteed the stability of the reconfigured closed-loop system by using the routh stability criterion, and was capable of solving bad steady precision problems that may occur in the reconfigurable system. Simulation results are provided to show the effectiveness of the proposed method by recover the performance of original system to a maximum extent.
