Abstract: The unknown input disturbance in a system of nonlinear ordinary differential equations is reconstructed from measurements of some of the state coordinates. A solution algorithm is proposed that is robust to information noises and computational errors. The algorithm is constructed using guaranteed control theory.

Key words: reconstruction, input disturbance, measurements of some coordinates, error estimation.
