%X In this paper, a concept of the degree of observable redundancy is proposed. The degree of the observable redundancy for the linear time-invariant systems is determined by compuling the rank of the matrices. It is shown that for the model based fault-tolerant control systems, if the measured signals possess the degree of observable redunancy of 1, the state feed-back control law can be reconstructed in the case of any single sensor fails and fault-tolerant control can be reserved.
