Robust fault detection in nonlinear systems: A Three-Tank Benchmark application

This report presents fault detection in nonlinear systems with application to nonlinear Three-Tank System Benchmark. A robust fault detection filter based on ℋ_∞ performance has been designed. Similarly three kinds of thresholds J_{th, RMS, 2}, J_{th, Peak, Peak}, J_{th, Peak, 2} are also designed. All the algorithms are successfully tested with the real process. The experimental results given in the end of paper elaborate the effectiveness of the proposed approach.
