Observability may also be characterized for steady state systems (systems typically defined in terms of algebraic equations and inequalities), or more generally, for sets in . Just as observability criteria are used to predict the behavior of Kalman filters or other observers in the dynamic system case, observability criteria for sets in are used to predict the behavior of data reconciliation and other static estimators. In the nonlinear case, observability can be characterized for individual v…

Web1 de jan. de 1988 · Observability is a global concept (Hermann and Krener, 1977) and a rigorous analysis of observability of nonlinear models is significantly more difficult than it is for linear systems (Mohler and Hwang, 1988).
