This paper interests to the reconfigurability of fault-tolerant control system based on the reliability analysis of components. The aim of this work is to present the need of reliability analysis in fault-tolerant control design. The admissibility of system reconfigurability with respect to the reliability constraints is considered in this research. This analysis proves that the control reconfigurability is a system property that not only related to the Gramian controllability but also to the overall system reliability. An admissible solution for reconfigurability indicator generation is proposed according to the reliability evaluation in degraded mode. A linearized aircraft model is considered as an example to illustrate this approach.
