Design and analysis of robust fault detection filter using LMI tools

In this paper, the robust fault detection filter design problem for linear time invariant (LTI) systems with unknown inputs and modeling uncertainties is studied. The basic idea of our study is to formulate the robust fault detection filter design as a H∞ model-matching problem. A solution of the optimal problem is then presented via a linear matrix inequality (LMI) formulation. The main result...

Robust Fault Detection Filter Design for Commercial Aircraft

The present article considers the application of robust H∞ filters for nonlinear aircraft models in cruise flight conditions. The achieved performance of various design scenarios are first compared with the best achievable lower bound, calculated using frequency-gridding method. The synthesis problem is than validated on the linear uncertain aircraft model, later on the nonlinear, high-fidelity...

Fault Detection Filter for Uncertain Fuzzy Systems: an Lmi Approach

The paper addresses the problem of designing a robust fault detection filter for an uncertain Takagi-Sugeno fuzzy models. The existence of a robust fault detection filter that guarantees i) the L2-gain from an exogenous input to a residual signal is less than a prescribed value and ii) the L2-gain from a fault signal to a residual signal is greater than a prescribed value is given in terms of t...
