Abstract :
The connections between the linear systems concepts of deterministic reconstructibility, stochastic reconstructibility, and estimability are described. Deterministic reconstructibility is shown to be a special case of stochastic reconstructibility, linking the notion of uncertainty reduction in terms of covariances to the deterministic definition. Examples are given to demonstrate properties of each definition and to compare them. Finally, a nonlinear extension of stochastic reconstructibility and a summary of its analysis is given to show the adaptability of our definition to more general cases. This work contributes to the larger study on concepts and applications of stochastic observability.
