Implementation of the proposed fault-tolerant control architecture requires data acquisition, feature extraction, fault detection and isolation, failure prognosis, adaptive control and V&V. Features will be extracted from time, frequency/spectral, and wavelet analysis. Bayesian reasoning, fuzzy logic, particle filtering and neural network techniques will detect and identify fault modes. Failure prognosis will be performed using particle filtering to estimate RUL. Anticipated failures will be mitigated by applying a time-varying multi-objective criterion function and appropriate constraints to determine optimal reconfiguration.
Related Applications: The proposed framework will directly apply to commercial power systems, hybrid-electric vehicles and future generation aviation platforms. This work is currently being applied to flight actuators and Navy power drive systems with support from the Air Force Research Laboratory (AFRL) and Office of Naval Research (ONR) respectively.
