Abstract

Consideration was given to diagnosis of engineering systems described by nonlinear dynamic models and operating in a destabilizing environment. A method of designing the mismatch generator on the basis of adaptive parity relations generated in real time by processing current controls and outputs of the diagnosed system was proposed. Robustness of the diagnostic procedures is provided by adaptation to slowly varying system parameters and use of the optimization approach.
