FDF Design for Data Reconstruction-Based NCSs

This chapter addresses the observer-based FDFFault Detection Filter (FDF) design for a continuous-time NCS by taking packet dropouts and network-induced delays into account. An observer-based FDFFault Detection Filter (FDF) and a reference residual model are introduced to construct a model for the continuous-time NCS. To reduce the time for fault detection, a new data reconstructionData reconstruction scheme is proposed and the corresponding closed-loop model is established. Based on the established models, FDF design criteria are derived to asymptotically stabilize the residual system.
