Order optimal real-time observers for completely observable control systems
Arkadii Kryazhimskii
Abstract
For a complety observable control system governed by a nonlinear ordinary differential equation, we consider dynamical (real-time) observation operators stable with respect to small input perturbations. We treat them as regularizing operators on an appropriate set of well-posedness. Two solutions order optimal with respect to the perturbation accuracy are described. The tool is based on the idea of guided models from the theory of closed-loop differential games, and the lower bounds for the unimprovable observation
accuracy.
