Abstract
A diagnosing apparatus for diagnosing a dynamic system by detecting a fault of the dynamic system. The diagnosing apparatus comprises: disturbance estimating means for estimating an integrated disturbance vector, which is the sum of external and internal disturbance vectors of the dynamic system, based on an internal state vector of the dynamic system; correlation calculating means for calculating a cross-correlation between the estimated integrated disturbance vector and the internal state vector and for separating from the integrated disturbance a component relating to the internal disturbance; and diagnosing means for specifying a corresponding fault portion of the dynamic system from the separated component relating to the internal disturbance.
