本文针对所选定的各种航程、紊流情况和飞行状态,计算了在(1-cosine)型离散突风的作用下本机和B707机的横侧向飞行品质。同时还考虑了本机驾驶员和操纵系统的影响。选定了在各种飞行状态下为使闭环系统获得稳定性能的KPMIN,KPMAX值和为使系统获得最小ISE的K_(pop)值。并认为在起飞和进场飞行状态下,在K_(pop)范围内作粗暴型控制即可使闭环系统获得比较满意的结果,而无需引入超前和滞后的作用。
In this paper, according to the selected range, turbulence conditions and flight status, the lateral flight quality of local and B707 aircraft is calculated under the effect of (1-cosine) discrete gust. It also takes into account the effects of the local pilot and the control system. The KPMIN, KPMAX values for the stability of the closed-loop system at various flight conditions and the K-pop values for obtaining the minimum ISE for the system are selected. It is also believed that rough control over the pop range in takeoff and approach flight conditions will result in more satisfactory results for closed-loop systems without the need to introduce lead and lag effects.
