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 ...

A novel extended state observer
ISA Transactions, 2015A novel extended state observer, which feeds back the output estimation error via both nonlinear and switching terms, is put forward for the first time in this paper. No longer neglecting the lumped uncertainty׳s first time derivative, the problem of disturbance observer design is transformed into the problem of state observer design in the presence of

STATE OBSERVERS FOR MONITORING GAS PIPELINES
IEE Proceedings D Control Theory and Applications, 1983The paper describes work performed in collaboration with the British Gas Corporation, in relation to the development of algorithms for monitoring the condition of high-pressure gas pipelines. The practical problem considered is that of reconstructing the pressure profile along a single length of pipe from pressure measurements at the end points and a ...

State Controller and State Observer
1989The design of the controllers described in the previous chapters was based on input/output models of the processes in form of difference equations or transfer functions, according Fig. 3.16a. Based on these models, input/output controllers could be designed either by parameter-optimization, chapter 5 or by structure-optimization, chapter 6 and 7.

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.

Observable Characteristics of Pure Quantum States
Physical Review Letters, 1991Summary: A pure state of a quantum-mechanical system, like a completely polarized state of light, is specified by the results of a few well-chosen experiments. We present a method for selecting such experiments, with applications to low-j angular momentum states.

Conditions of Observation and States of Observers
The Philosophical Review, 1956NORMALLY when we talk about perception and about what is perceived, we use material-object language. That is, we talk as if we could and did perceive-see, touch, hear, taste, smell-external physical objects which constitute our evironment. At the same time we admit that sometimes we are liable to perceptual errors and to hallucinations.
