  • Abstract
    A new approach, namely the mixed H-/H∞ estimation, to robust fault detection problem for dynamic systems is presented. The H-/H∞ fault detection observer is designed to minimise effects of disturbances on the residual of the observer whilst maximising the effects of faults on the residual signal. This takes into account the robustness of a fault detection observer against disturbances and sensitivity to faults simultaneously. The H-/H∞ fault detection observer problem is actually a mixed H-/H∞ estimation problem. The latter can be further reformulated as a constrained H∞ estimation problem and solved in a mixed linear matrix inequality (LMI) setting.
