| Abstract: | The fault detection problem in sampled data systems is studied. The key point is to introduce operators to describe the influence of the continuous time unknown input signal and fault signal on the discrete time residual signal, respectively. Based on this, the robustness and sensitivity problem can be defined as an optimization problem and the corresponding solution is derived. The simulation results illustrate the effectiveness of the proposed approach. |

| Keywords: | Fault detection sampled data system residual generation robustness sensitivity |
