<p>A system (902) for empirically diagnosing a condition of a monitored system (918). Estimates of monitored parameters (920) from a model of the system (922) provide residual values (924) that can be analyzed for failure mode signature recognition (916). Residual values can also be tested for alert (non-zero) conditions (927), and patterns of alerts (914) thus generated are analyzed for failure mode signature patterns (916). The system (902) employs a similarity operator for signature recognition (916) and also for parameter estimation (924). Failure modes are empirically determined, and precursor data (930) is automatically analyzed to determine differentiable signatures for failure modes.
