【 摘 要 】

The design of non-destructive testing systems relates to the solution of the problem of analysis of observability. It is the assessment of the opportunities of the set of measured parameters to diagnose the object, to identify emerging defects and the specific modes of operation. The term 'observability' in control theory does not correspond to the tasks of diagnosis and requires the model of the object's state. The proposed concept of 'diagnostic observability' allows to use this term in tasks which aren't related to the control. It doesn't require the model of the object's state, and realizes the estimation on the array of measurements performed for various diagnosed states of the object. The set of diagnostic state variables is determined as coordinates of diagnostic orthogonal space. The proposed principle of diagnostic observability is determined by the method of construction of the space of the diagnostics and by the analysis of the images of states of object. It can become a new basis for building an effective universal adaptive systems of non-destructive testing of complex technical and other objects.
