Fault isolation filter design for linear systems

This paper is concerned with the problem of detecting and isolating faults. We provide a method to design a fault isolation filter such that multiple faults can be detected and isolated. This design procedure guarantees to isolate up to n faults, where n is the dimension of the system. In particular, we are interested in the application of the developed scheme to a d.c. motor driving a centrifugal pump driven. Extensive computer simulations demonstrate the detectability and isolability of faults by the detection filter in the occurrence of multiple faults in the motor-pump dynamic system
