The system simulation technology is applied to the fault detection and diagnosis (FDD). The idea of solving theoretical trajectory deviation through online interaction of measured information is proposed. The FDD logic structure based on system simulation is established. For MIMO system and linear dynamic measurement architecture The fault identification algorithm with good statistical properties provides a new technical approach for fault detection, fault identification, fault time determination and fault pattern recognition.The ideas and methods in this paper not only can be used for fault detection and diagnosis of CVDS, but also for large-scale complex System failure analysis also has a reference and reference value
