In terms of functional dependence, the description of
observable functions in nonlinear dynamical systems, which are
analytic with respect to phase variables, is obtained. For
processing of measurements, integral operators are used, which
provide certain noise stability of operation of phase state
reconstruction. The analogue of the duality theory known for
linear problems of observation and control is developed.
Computing schemes for nonlinear observability problem are
