进行机翼故障情况下的飞行包线估算可为驾驶员正确操纵和包线保护控制提供必要的信息.考虑到飞机机翼故障的动力学特点,提出一种动态飞行包线估算方法.建立故障参数模型,应用最小二乘辨识算法进行气动参数辨识与故障诊断;基于参数辨识结果估算飞行包线;根据故障特点,分别对系统进行配平计算,在每个配平点建立飞行包线数据库,根据故障诊断结果实时调用包线库中的数据,形成当前时刻的飞行包线. The calculation of the flight envelope in case of wing failure can provide the necessary information for correct driver control and envelope protection control.A dynamic flying envelope estimation method is proposed considering the dynamic characteristics of aircraft wing failure. Parameter model and aerodynamic parameter identification and fault diagnosis using the least-squares identification algorithm. The flight envelope is estimated based on the parameter identification results. According to the fault characteristics, the system is separately calculated and the flight envelope database is established at each grading point. According to the fault The diagnostic results call the data in the envelope library in real time to form the flight envelope of the current moment.
