Observer-based fault detection for T-S fuzzy systems subject to measurement outliers

This paper is concerned with the problem of fault detection (FD) for T-S fuzzy systems with measurement outliers. A new fuzzy FD observer with adaptive saturation of output errors is first constructed to reduce the effect of measurement outliers on the error systems and the residual signals. Then, by establishing a suitable non-differentiable Lyapunov function, sufficient conditions in terms of linear matrix inequalities (LMIs) are derived to...
