A comprehensive validation approach of PHM system's diagnosis and verification

This paper provides a comprehensive validation method of PHM system's diagnostics and predictive capability. It consists of five steps: including the parameter selection of PHM comprehensive validation; the sample database creation of PHM comprehensive validation; the samples processing methods of PHM comprehensive validation; the sample injection method of PHM comprehensive validation; the assessment results of PHM comprehensive validation. It makes the fault diagnosis and fault prediction technology of PHM system together, eventually forming a comprehensive validation approach which fills the gap in the field of testability.
