چکیده مقاله
In this research, fault detection for network control systems NCSs using unknown input observer UIO is proposed The considered system have multiple communication delays and time varying uncertainty First, the residual signal is obtained via a UIO, and then residual evaluation function is computed The Lyapunov approach is exploited to ensure the stability of the observer Moreover, H∞ index is used to reduce the effect of perturbation in the residual signal The result of observer design is formulated as linear matrix inequalities LMIs Finally, the effectiveness of the proposed method is shown by a numerical example
