Functional diagnosis of the nonlinear dynamic delay systems

Consideration was given to the problem of functional diagnosis of the nonlinear dynamic delay systems. Its solution implies design of redundancy relations whose verification underlies conclusions about system operability and the kind of system defect. For the systems obeying differential equations with a polynomial right-hand side, a method was proposed for designing the redundancy relations. It admits that some or all constant coefficients of the polynomials are unknown.
