摘　　要：应用目前国外许多著名飞机公司及研究机构关于起飞着陆阶段的驾驶员诱发振荡（ＰＩＯ）问题的预测方法和设计判据，对某数字电传飞控系统起飞着陆控制系统进行了纵向ＰＩＯ研究。经多种设计准则的迭代优化及ＰＩＯ预测方法的评定，使所设计的系统性能处于最优区，无纵向ＰＩＯ趋势。The predict methods and design criteria on the Pilot-Induced Oscillation (PIO ) of some internationally known aircraft companies and research institutes areintroduced. The longitudinal PIO of a certain digital fly-by-wire take-off andlanding system is studied. The simulation results are examined through some design criteria on PIO, the system performances are lie in the optimal design zone, no longitudinalPIO tendency. It will give a meaningful reference to a new aircraft development.
