Abstract: A reconfigurable redundancy management strategy for a triplex DFBW flight control system is discussed in this paper. The strategy consists of redundancy and control law reconfiguration after 1 st, 2 nd and 3rd failures. Every part of the system uses both the comparison monitored and the self-tested schemes. With the combination of two monitors schemes the functional range of reconfigurable strategy can be expanded, and high system reliability can be achieved. The computer verification results for reconfigurable strategy are presented. The reconfigurable management software has been designed, and the architectures for all of software moduls and its interfaces are introduced. It has been shown that the key factor impact on feasibility of the strategy is the data transmitted rate, especially the across-channel data transmitted rate.
