A unified model is proposed to capture four sources of these uncertainties, namely, the sensor saturation, the signal quantization, the general medium access constraint, and the multiple packet dropouts. A simultaneous consideration of these issues reflects the practical networked systems much more closely than the existing works. The goal of this paper is to design a fault detector such that, for all unknown input, control input, and uncertain information, the estimation error between the residual and the fault is minimized. Using the switched system approach and some stochastic analyses, a sufficient condition for the existence of desired fault detector is established and the fault detector gains are computed by solving an optimization problem. Two numerical examples are given to show the effectiveness of the proposed design. © 1963-2012 IEEE.||Source Title:||IEEE Transactions on Instrumentation and Measurement||URI:||http://scholarbank.nus.edu.sg/handle/10635/82395||ISSN:||00189456||DOI:||10.1109/TIM.2013.2272865|
