Fault Detection for Delta Operator Based Network Control Systems

The problem of fault detection for the delta operator has formulated network control systems with uncertain network-induced delay is considered.Based on the traditional observer-based robust fault detection filter using the shift operator,a new filter model to fault detection for the delta operator formulated network control systems.The solvable condition of the filtering optimization problem and further the solutions are derived by linear matrix inequalities.The simulation results show the effectiveness of the proposed approach.
