Abstract :
This paper describes the application of fuzzy logic to the analysis of residuals generated using an observer scheme for the three tank benchmark. Two methods of residual analysis are investigated; fuzzy inference (i.e. rule based) and fuzzy clustering. The aim of both of the schemes is to simplify the task of the operator in determining the state of the plant (and any necessary action) by improving the presentation of the fault /no-fault information. Simulation results are presented for the three tank benchmark, and the two methods compared as to their effectiveness for residual evaluation in terms of isolation ability and ease of design.
