The invention relates to a robust fault detection method of a discrete time networked system with random packet losses. The object is a time-varying system with unknown disturbance and a nonlinear term, parameters of the system vary along with time and meet norm bounded conditions, the nonlinear term meets fan-shaped domain bounded conditions, and the unknown input is any energy bounded signal with unknown statistical property. Through state augmentation, an original fault detection problem can be converted into a robust H8 filtering problem, namely, a robust fault detection filter is designed, and for any allowed time-varying parameter and external disturbance and all possible data losses, the difference between output of the fault detection filter and a fault signal is made to be as small as possible in the sense of H8. The Lyapunov function method is used for proving that a whole fault detection system is stable in asymptotic mean square and meets the corresponding H8 disturbance attenuation ...
