摘要
The problem of fault detection for the delta operator formulated discrete time system is considered. Based on the traditional Luenberger observer using the shift operator, a new observer design approach to fault detection for delta operator system is proposed. Both the existence conditions and explicit expression of the desired observer are developed. The algorithm of observer-based fault detection for delta operator systems is also given. The simulation results show the effectiveness of the proposed approach.
