| Abstract: | A design of fault detection observer based on optimal sensor location is proposed.The problems in designing fault detection observer and its optimal design problems based on an optimal sensor location are formulated for the linear time invariant system.Measurements are selected optimally,a minimum total measurement cost can be achieved when the system is designed to be as sensitive as possible to faults and simultaneously as robust as possible to the unknown inputs such as disturbance.The simulation results illustrate the effectiveness of the proposed approach. |
