Adaptive thresholding for fault detection in networked control systems

This paper studies the problem of fault detection in networked control systems. In the residual generation, the effect of the networked induced bounded delays as well as the noise is reduced. The minimization of false alarm rate caused from unknown inputs as well as the variation of control inputs is achieved in the residual evaluation stage. This includes the design of an adaptive threshold. An illustrating example is given to show the efficiency of the obtained results.
