Abstract: | Hardware-in-the-loop simulation is an important step to turn the algorithm from theory to practical, the development of
hardware-in-loop simulation platform for aeroengine fault diagnosis algorithm is in the primary stage now. Based on the existed nonlinear
model of civil high bypass ratio turbofan engine, the xPC-based automatic code generation technology was used to build a hardware-in-theloop
real-time simulation system of engine fault diagnosis device based on IPC and DSP hardware, the performance parameters of platform
and the operation process were described. A fault diagnosis algorithm was proposed and the hardware-in-loop verification was carried out.
An evaluation criterion of fault diagnosis algorithm based on the platform was put forward |
