In the work we propose an algorithm for parametric identification of nonlinear objects of
control. The algorithm is based on the idea of phase space extension of the identified ob-
ject vector of unknown parameters. We use the matrix of operators, linearization of ex-
tended nonlinear system of equations according to the scheme of Newton–Kantorovich,
suggesting some iterative process of finding identifiable parameters on the criterion that
ensures the proximity of the release of the real object to the output of its mathematical
model. The algorithm application is illustrated by an example of parameters identifica-
tion of the electro-hydraulic drive.
