X A − F X = G C , where A and C are given and X, F, and G are to be found will be called the Sylvester-observer equation.
The name “Sylvester-observer equation” is justified, because the equation arises in construction of an observer and it is a variation of the classical Sylvester equation (discussed in Chapter 8):
How does an observer work in control system?
Observers can be used to augment or replace sensors in a control system. Observers are algorithms that combine sensed signals with other knowledge of the control system to produce observed signals..
What are the different types of state observers?
The considered observers include Luenberger observer, Kalman observer, unknown input observer and sliding mode observer..
What does an observer do in a system?
An observer is an algorithm that combines feedback from the sensor with other information about the control system to produce observed feedback signals that are more accurate and more reliable than the basic feedback signals.Aug 27, 2021.
What is an observer in control system?
In control theory, a state observer or state estimator is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system..
What is the difference between state estimator and observer?
An observer is a filter used to get the states information if the system is deterministic. An estimator is a filter to get the states information if the system is stochastic. Examples: Luengberger structure is an observer ; Kalman filter is an estimator..
What is the observer theory of control?
In control theory, a state observer or state estimator is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system..
Why do we need state observers?
In control theory, a state observer or state estimator is a system that provides an estimate of the internal state of a given real system, from measurements of the input and output of the real system. It is typically computer-implemented, and provides the basis of many practical applications..
A full-state observer is used to estimate all the states of the system. The observer can be designed as either a continuous-time system or a discrete-time system. The characteristics are the same, and the design processes are at least very similar and in some cases identical.
Observers are digital algorithms that combine sensor outputs with knowledge of the system to provide results superior to traditional structures, which rely wholly on sensors. Observers have been used in selected industries for years, but most books explain them with complex mathematics.

Military role for observing artillery strikes and directing them to their targets
An artillery observer,artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see.
Observer is a psychological horror video game developed by Bloober Team
2017 video game
Observer is a psychological horror video game developed by Bloober Team and published by Aspyr. It was released for Microsoft Windows, PlayStation 4 and Xbox One in August 2017, followed by versions for Linux, macOS and Nintendo Switch. An upgraded and expanded version called Observer: System Redux was released in November 2020 for Windows, PlayStation 5, and Xbox Series X/S, for Amazon Luna in March 2021, and for PlayStation 4 and Xbox One in July 2021. Observer follows Daniel Lazarski, a detective known as an Observer, who can hack people's minds as a method of interrogation.
Positive systems constitute a class of systems that has the important property that its state variables are never negative, given a positive initial state. These systems appear frequently in practical applications, as these variables represent physical quantities, with positive sign.
