Abstract A new approach is presented for selecting alarm thresholds in a simple fault detection system. Bounds are computed on the magnitudes of the minimum detectable fault and the maximum non‐detectable fault. The use of the 2‐norm for this calculation results in a linear matrix inequality (LMI) problem. An example is presented and a filter design is proposed that enhances the ability to distinguish between a fault and a disturbance. © 1998 John Wiley & Sons, Ltd.
