Abstract
The problem of functional observer design for dynamic systems described by nonlinear differential equations under external disturbances is considered. Relations that allow design of the observer of a reduced-order-dimensional invariant with respect to the disturbances and estimating the prescribed function of the state vector are derived. Theoretical results are illustrated by an example.
