摘要

This paper presents a formulation for a class of robust fault detection problems, and its corresponding solution approach. In order to provide insight into the robust algorithm, one needs to consider the past and understand its historical origins in optimal fault detection, where it is assumed that both plant and noise models are accurate. The deleterious effect of plant model uncertainties on the performance of the optimal tests is illustrated, thus motivating the idea of robust fault detection, which makes use of robust game theoretic (H_infinity) or risk sensitive estimators. These estimators provide test residuals or statistics that are insensitive to uncertainties, but still sensitive to failure modes. The paper concludes by motivating and suggesting new ideas for future research.
