Abstract: The paper considers the filtration algorithm which feedback uses not only current residuals but also their integrals. It is shown that the integral residuals allow to derive unbiased estimates of phase coordinates even under unknown perturbations.

Keywords: mathematical models of motion and perturbation, Kalman filtering algorithms, integral of the residual, unbiased coordinates estimates.
