Abstract
This paper discusses the problem of fault diagnosis under multiple sequential faults occurrence. In industrial applications this type of fault is the most common since the continuous operation of the systems/processes is required. The fault diagnosis algorithms should cope with such type of multiple faults, but degradation in its fault isolation capabilities is introduced until the point that they should be stopped. A new algorithm to design the fault diagnosis to tolerate multiple sequential sensor faults is proposed. Finally, an example based on the rain-gauge sensor network of the Barcelona sewer system will be used to illustrate how the associated fault diagnosis system behave under multiple sequential faults occurrence and to test the proposed algorithm.
