Dynamic Reconstruction of System Disturbances Using Inaccurate Discrete Measurements of Phase Coordinates

Resumo

This paper studies the dynamic reconstruction of unknown disturbances for a system of differential equations that is nonlinear in phase variables. In the case of imperfectly measured phase coordinates within the given intervals, we develop a reconstruction algorithm with the integration of the feedback control and optimal programmed control. The algorithm is stable against data noises and computational errors. An illustrative example is given.
