Models of dynamic systems are considered with regard to the tasks of diagnosing real-time complex information processing and control systems. The problem of diagnosing is one of the most important in the practice of development technical systems. It is important to note that symmetry principles are used in this work, in particular, to formulate the basic approach to diagnosing complex systems. This approach assumes that the components of a system are allocated to the levels based on inclusion relations. In this case, level-based diagnostic tools with their own models can be synthesized, and the relations between them are characterized by the symmetry feature. Problems of both functional and test-based diagnostic methods are discussed. Particular diagnostic methods may also involve symmetry principles since, in a certain sense, they operate with symmetric notions of observability and controllability of a dynamic system. The implementation of the proposed methods is illustrated by an example of their application to a navigation system of an autonomous underwater vehicle.

The paper discusses the problems of troubleshooting in onboard computing and control systems. Herewith the approaches based on the methods of functional and test diagnostics are analyzed. Both approaches involve the introduction of redundancy, which in fact is a dynamic software model of the systems being diagnosed. In the case of functional diagnostics, a full-fledged model is used that forms the basis for diagnostic observers; in the case of test diagnostics, it is a simplified event model.
