Abstract:Transient faults are the dominant fault forms causing accidents in the control systems, and the fault recovery is
a critical measure to ensure the system safety. Therefore, the typical methods of transient faults recovery and safety control
based on active redundancy and system model analysis are summarized. Then the classical methods applied to recover the
transient faults in communication networks, system nodes and the whole networked control systems(NCS) are surveyed.
Finally, the prospect of the development of transient faults recovery and safety control in NCS is given.
