摘要
针对飞机机载智能故障预测与健康管理(PHM)系统工程化技术成熟度低、开发平台匮乏,尤其缺少设计与验证的有效手段,以无人机飞控系统PHM控制律模型设计为例,采用基于模型的系统工程方法实现飞控系统的全面诊断和预测功能。通过构建基于MBSE的飞控系统PHM开发平台模型及模型联合仿真实现了PHM开发平台的功能结构验证,建立了基于模型的软件标准模块库,利用Simulink和状态机进行系统架构模型与子模型的搭建与仿真,仿真结果表明基于MBSE的飞控系统故障模式及影响分析(FMEA),能及早发现飞控系统PHM架构设计中的故障隐患,及时进行完善,提高某型无人机飞控系统PHM的可靠性。
In view of the low maturity of aircraft airborne PHM system engineering technology,the lack of development platform,especially the lack of effective means of design and verification,this paper takes the PHM control law model design of UAV flight control system as an example,and uses the model-based system engineering method to realize the comprehensive diagnosis and prediction function of flight control system.By constructing the PHM development platform model and model joint simulation of flight control system based on mbse,the functional structure verification of PHM development platform is realized,the model-based software standard module library is established,and the system architecture model and sub model are built and simulated by using Simulink and state machine.The simulation results show that the failure mode and impact analysis(FMEA)of flight control system based on mbse.It can find the hidden trouble in the PHM architecture design of the flight control system as soon as possible,improve it in time,and improve the reliability of the flight control system PHM of a certain UAV.
