Fault Diagnosis and Hardware-in-the-loop Testing of Microturbine Sensor Based on Improved Kalman Filter

In order to solve the problem of fault diagnosis of microturbine sensor signal under variable working conditions,a fault diagnosis method based on a bank-of-Kalman-filter was proposed. The model-based design method was used to develop the simulation model of the Simulink microturbine component level based on the V-development process. The Fault Diagnosis and Isolation(FDI)system of the sensor was designed under the variable load condition. The model and the FDI system were integrated and verified based on the full digital simulation platform and the hardware-in-the-loop simulation platform. The results show that the full digital simulation and hardware-in-the-loop simulation based on MBD method have high consistency, and can quickly realize model transformation and verification,which provides powerful support for the development of microturbine control algorithm and hardware-in-the-loop verification.
