Abstract:
An H-infinity, approach to fault detection in sampled-data systems is presented. At first a discrete-time fault detection system is constructed and the dynamics of the residual generator is analyzed. Then an operator is introduced from the viewpoint of fault detection to describe quantitatively the influence of the continuous-time unknown inputs and faults on the discrete-time residuals. Finally the parameter of the residual generator is optimized, so that the fault detection system is robust to the unknown inputs and simultaneously sensitive to the faults.
