多因素耦合飞行情形的复杂系统建模与仿真方法

针对多因素耦合飞行情形动态复杂性强、易诱发"不可逆"灾难性事故等特点,首先分析了不利因素对飞行安全的影响,并对不利因素耦合类型进行归类,然后建立了以飞机六自由度全量仿真模型和驾驶员操纵模型为基础的人-机系统模型;重点研究了特殊情况下驾驶员的失误模型,建立了驾驶员滞后失误时间和反操纵失误的定量模型、自动驾驶仪可靠性模型、传感器故障通用模型和过载传感器故障模型。最后,以GJB 626A-2006中的"自动驾驶仪低限高度自动拉起"风险科目为例,对人-机不利因素双耦合和机-机不利因素双耦合2种情形进行了仿真分析,结果验证了该方法的可行性和有效性。

Modeling and Simulation Method of Complex System in Multi-factor Coupling Flight Situations

Multi-factor coupling flight situations have the characteristics of strong dynamic complexity and always leading to "irreversible" chain reaction disasters. To research the modeling and simulation method of pilot-aircraft complex system in coupling flight situations, the impact of disadvantageous factors on flight safety is analyzed, and the factor coupling types are classified. Pilot-aircraft basic model is set up based on non-linear six-degree-of-freedom mathematical model and pilot manipulation model. Special researches are conducted on the modeling of pilot failure model. The delay time failure is defined and modeled, and reverse manipulation model is established. The robot pilot reliability model, sensor general malfunction model and overload sensor malfunction model are established. The subject of "automatic pull-up using robot pilot in the lowest permitted height" in GJB 626A-2006 is used for example, in which the "human-machine" and "machine - machine" disadvantageous factor double coupling situations are simulated and analyzed to verify the feasibility and practicability of the method.
