System Fault Identification and Control Method Based on Functional Model

In this chapter, the system fault identification and control method is developed based on the function model for the integrated design of both functional performance and hexability of the system-level product. First of all, the identification method of component functional faults in the total domain is established for function preservation, and furtherly on the basis of this, the identification method of component physical faults in the total domain is established, combined with the mapping relationship between the functional and the physical models. Then, for solving the fault emergence problem during the system integration process, the identification methods of the interface fault, transmission fault and error propagation fault are presented, respectively. Finally, combined with the fault closed-loop mitigation control process, the closed-loop fault mitigation and control method and fault mitigation decision method are developed respectively for the component faults to system faults.
