Fault monitoring and diagnosis of inertial apparatus based on time-frequency analysis pattern recognition
Guangjun Chen · Electronics Optics & Control · 2006
The basic principle of detecting signal with time-frequency distribution is briefly presented.Then a method based on the Pseudo-Margenau-Hill Distribution(PMHD)and the Pattern Recognition(PR) is put forward for fault monitoring and diagnosis of the inertial apparatus.Result: The experimental result shows that the method can implement fault type identification of the inertial apparatus,and realize status monitoring and fault isolation.Conclusion: This method is very useful in engineering.
