本文以歼×机为例,用根轨迹法配合特征矢量法,探讨飞机进场着陆前,为保持飞机侧向航迹,驾驶员或自动器应采用的操纵规律。文中分析了各种反馈信号对飞机侧向航迹动态特性影响,最后得出采用δ_x=k_x~(ωx)·ωx+k_x~γ·γ-k_x~ψψ+k_x~z·Z调节规律,控制飞机侧向航迹稳定性较好。 In this paper, an example is J-X machine, which uses root locus method and eigenvector method to explore the operating rules that drivers or robots should use to maintain the lateral track of the aircraft before landing. In this paper, the influence of various feedback signals on the dynamic behavior of the aircraft’s lateral track is analyzed. Finally, the regulation of δ_x = k_x ~ (ωx) · ωx + k_x ~ γ * -k_x ~ ψψ + k_x ~ Aircraft side track stability is better.
