Abstract :
Studies the fault detection (FD) problem for uncertain sampled-data systems. A direct design approach of the discrete-time FD system is presented which takes the intersample behavior into account. The resulting FD system achieves the best compromise between the sensitivity to the faults and the robustness to the unknown disturbances and model uncertainty.
