Reconstruction of unknown characteristics in a third-order system

Abstract

The article considers dynamic identification of unknown characteristics in a third-order system. A realtime algorithm is proposed for the solution of the problem. The algorithm relies on constructs from stable dynamical inversion theory, which combines methods of the theory of ill-posed problems and positional control theory. In the proposed procedure, the reconstruction algorithm is represented as a control algorithm for some artificial dynamical system - a model. The model control is adapted to current observations so that its realization eventually "approximates" the unknown input. © 2013 Springer Science+Business Media New York.
