A Distributed Fault Detection Filtering Approach for a Class of Interconnected Continuous-Time Nonlinear Systems
No full textThis paper develops a filtering approach for distributed
fault detection of a class of interconnected continuoustime
nonlinear systems with modeling uncertainties, disturbances
and measurement noise. A distributed fault detection scheme
and the corresponding adaptive thresholds are designed based on
filtering certain signals so that the effect of the measurement noise
and of the disturbances is attenuated, allowing for the design
of less conservative thresholds. A key novelty of the proposed
work is that a general class of filters can be embedded into
the design of the residual and threshold signals in a way that
takes advantage of the filtering noise suppression properties. The
analysis of the proposed distributed fault detection scheme shows
that the derived thresholds guarantee that there are no false
alarms and characterizes quantitatively the class of detectable
faults. Further rigorous detectability analysis provides results
regarding the magnitude of the detected faults, an upper bound
on the detection time and the relation of the detection time
with respect to the order and pole locations of the filters used.
Simulation results are used to illustrate the proposed distributed
fault filtering approach
