A state observer for nonlinear systems
IEEE Transactions on Automatic Control, 1999Summary: A state observer design methodology for a class of nonlinear systems is proposed. The nonlinear observer design methodology is, in fact, an extension of linear observer design techniques using transformations related to linear observability matrices.

Filtering with discrete state observations
Proceedings of the 36th IEEE Conference on Decision and Control, 1999In this paper, a finite state signal Markov chain is meant to model the possible orientations (for example, forward, up, down, right turn, left turn) of a target. The states of the Markov chain are observed indirectly through a process with ``information'' that has two sources, an independent counting source (noise), and a source that contains ...

Delayed input and state observability
2008 47th IEEE Conference on Decision and Control, 2008This paper considers the concept of input and state observability, that is, conditions under which both the unknown input and initial state of a known model can be determined from output measurements. We extend previous results on input and state observability for discrete-time systems by considering a more general framework. Particularly, we introduce

Behavior States Are Real and Observable
American Journal on Mental Retardation, 2000Mudford, Hogg, and Roberts (1999) published additional concerns about their failure to achieve interobserver agreement on adults with mental retardation when using an experimental, 13-category behavior state code we earlier provided to them at their request.

Observation of ‘‘Tamm states’’ in superlattices
Physical Review Letters, 1990We have observed localized surface states (Tamm states) intentionally introduced in AlGaAs/GaAs superlattices by a terminating layer of AlAs. The formation of these states is manifested by excitonic interband transitions in photoluminescence excitation spectra.

A robust state observer scheme
IEEE Transactions on Automatic Control, 2001Summary: This note proposes a new approach to robust state observer construction. The scheme is derived by including an extra term and adopting the Lyapunov stability theorem, and requires the solution of an algebraic Riccati equation. The scheme is implemented in a gas-fired furnace system example. Satisfactory results are obtained, though, in general,

State estimation with biased observations
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 1999State estimation is difficult when the system has multiple modes of operation. Modal transitions create discontinuities in the reference point for the local state variables. The uncertain reference point increases the ambiguity in the state measurement. The paper presents an estimation algorithm that can be used in multimodal applications.

This chapter describes the basic structure of any quantum-mechanical theory. The first step in the mathematical formulation is to associate a suitable Hilbert space with a physical system. The vectors in that Hilbert space (or rather the one-dimensional subspaces spanned by these vectors) describe the possible states of the system.

Abstract The states and the observables are basic concepts in the description of a physical system and their description has undergone a drastic fundamental change in the transition from the classical theory to the quantum theory.
