Abstract

This paper addresses Fault Detection (FD) problem of a class of nonlinear systems which are monitored via the communications networks. A sufficient condition is derived which guarantees exponential mean-square stability of the proposed nonlinear NFD systems in the presence of packet drop, quantization error and unwanted exogenous inputs such as disturbance and noise. A Linear Matrix Inequality (LMI) is obtained for the design of the fault detection filter parameters. Finally, the effectiveness of the proposed NFD technique is extensively assessed by using an experimental testbed that has been built for performance evaluation of such systems with the use of IEEE 802.15.4 Wireless Sensor Networks (WSNs) technology. An algorithm is presented to handle floating point calculus when connecting the WSNs to the engineering design softwares such as Matlab. © 2011 IEEE.
