基于Matlab/Simulink的直/发一体化建模 与故障诊断

针对目前航空发动机控制系统设计仅以单一的发动机为对象,没有考虑直升机与发动机之间的动态耦合的问题,基于Matlab/Simulink高级图形的仿真条件,建立了1种适用于快速控制原型的UH60直升机/T700发动机一体化综合模型,从而为发动机故障诊断提供可靠仿真平台。仿真结果表明:在直升机与涡轴发动机耦合因素影响条件下,基于改进卡尔曼滤波器,可实现发动机气路部件的故障诊断,并验证了其有效性。

Integrated Helicopter/Turbo-shaft Engine Modeling and Fault Diagnosis Based on Matlab/Simulink

Conventional engine control system is only designed for a single engine object, without considering dynamic coupling between the helicopter and engine. Based on the simulated conditions of Matlab /Simulink advanced graphics, an integrated helicopter UH60/T700 turbo-shaft engine model could be used in rapid control prototype was built , which provides a reliable simulation platform for engine fault diagnosis. The results show that the fault diagnosis of engine components was improved to be effective based on the advanced Kalman filter, which considering the helicopter and engine coupling factors.
