The problem of fault detection for the Lipschitz nonlinear time-delay networked control systems with packet dropouts and access constraints is concerned. By using the linear matrix inequality technique, a fault detection filter is designed. Then, a new threshold calculation method is proposed, so that the residual evaluation function can quickly exceed the designed threshold and the residual error can achieve minimum when actuators fault occur with disturbance. Finally, simulation results show that the proposed method can detect fault faster than some others.
