Reconstruction of Disturbances in a Nonlinear System from Measurements of Some of the State-Vector Coordinates

Аннотация

The problem of reconstructing an unknown disturbance of a nonlinear system of ordinary differential equations from inexact measurements of some of the state coordinates is considered. A solution algorithm robust to noises is proposed that combines constructions of dynamic inversion and guaranteed control theories. The algorithm consists of two blocks: one dynamically reconstructs the unmeasured coordinates and the other reconstructs the disturbance.
