A Fault Isolation Algorithm for the case of Multiple Faults and Multiple Fault Types
A Fault Isolation Algorithm for the case of Multiple Faults and Multiple Fault Types
Mattias Nyberg
Given a number of thresholded residuals, an algorithm for finding the
diagnoses, i.e. possible faults, is presented. The algorithm is based
on ideas used in diagnosis algorithms from the field of AI. It is
capable of handling the case of multiple faults and multiple
fault-types per component. The number of multiple faults is
exponential in the number of components. To handle this complexity
problem, logical formulas are used to efficiently represent
diagnoses. The formulas obtained can easily be used to derive the set
of all diagnoses or the set of most probable diagnoses.
