自动飞行系统飞行模式操作验证方法研究

Research on verification method for flight mode operation of auto-flight system

现代民用飞机的自动飞行控制系统是主要的人机交互系统之一,其飞行模式操作控制功能由两大物理部分组成:FMCP硬件与自动飞行控制软件。对于复杂的人机交互功能的验证,需要采用面向开发过程的模型验证方法,首先由系统功能层级到功能模块层级逐级分解飞行模式操作控制功能开发架构,进而从功能模块层级到系统功能层级自下而上设计飞行模式操作控制功能验证架构,最后针对功能验证架构中的集成模型测试阶段,以FMCP速度视窗功能为例,通过对所有相关的人机操作进行分类定义,分别定义了速度目标值的状态转换与动作响应,进而针对定义梳理出完整的速度目标值状态转换与动作响应矩阵,矩阵中的每一个表格均对应着速度目标值的状态转换或者动作操作及其对应的响应情况。为自动飞行模式操作控制的集成模型验证提供了参考。

The automatic flight control system of modern civil aircraft is one of the primary human-machine interac-tion systems,and its flight mode operation control function consists of two main physical components:FMCP hard-ware and automatic flight control software.For the validation of complex human-machine interaction functionalities,an approach oriented towards the development process is necessary.Firstly,the development architecture of flight mode operation control functions was decomposed step by step from the system functional level to the functional module level.Then,an architecture for verifying the flight mode operation control functions was designed from the functional module level to the system functional level,in a bottom-up manner.Finally,focusing on the integrated model testing phase within the functional verification architecture,taking the example of FMCP speed window func-tion,all relevant human-machine interactions were categorized and defined.The state transitions and action respon-ses for speed target values were defined separately,and a comprehensive matrix of state transition and action re-sponse of speed target value was sorted out based on the definitions.Each table in the matrix corresponds to the state transition or action operation of the speed target value and its corresponding response situation.This provides a reference for the integrated model validation of automatic flight mode operation control.
