Fault tolerant control using augmented fault detection filter

In this paper, an passive fault-tolerant control system (FTCS) strategy is presented for linear dynamic systems. The detection and isolation of one jumps is achieved by the Kalman filter designed under a dead beat constraint allowing the maximum adaptivity of the fault magnitude estimation in the case of abrupt change. By using the state estimation corrected by the estimation of jumps we describe a integrate fault tolerant control system via a particular LQG approach.
