On Convergence of the Linear Extended State Observer
IEEE International Symposium on Intelligent Control, 2006Motivated by the gap between theory and practice in control problems, Linear Active Disturbance Rejection Control (LADRC) addresses a set of control problems in the absence of precise mathematical models. LADRC depends on the quick convergence of a unique state observer, known as the extended state observer, proposed by Han.

Extended State Observer for Nuclear Reactors
2018 Annual American Control Conference (ACC), 2018An extended state observer (ESO) for nuclear fission reactors is proposed in this paper, which is suitable for reactor monitoring. This ESO is proposed in the natural coordinates of a fission reactor, and can provide globally bounded estimation for the nuclear reactor state-variables and the disturbances induced by the external reactivity and secondary

Fuzzy extended state observer for the fault detection and identification
ISA Transactions, 2022This paper introduces a novel methodology to detect and identify faults for a class of autonomous nonlinear systems. In the proposed design, a fuzzy extended system observer (FESO) based on the Mandami-type fuzzy system is used to estimate the fault that is considered to be the extended system state.

Disturbance observers and extended state observers for marine vehicles: A survey
Control Engineering Practice, 2022The operation performance of marine vehicles (MVs) is significantly vulnerable to external disturbances induced by wind, waves, and ocean currents in complex marine environments. Disturbance estimation is a fundamental issue in MV motion control, and various disturbance estimation methods are explored for high-performance motion control of MVs.

Event-Triggered Extended State Observer
2021Based on the performance analysis on discrete-time ESO and the gain parameter design provided in Chap. 2, we consider the event-triggered extended state observer (ET-ESO) design for a continuous-time nonlinear system with uncertainty and disturbance in this chapter.

Capabilities of extended state observer for estimating uncertainties
2009 American Control Conference, 2009The capabilities of extended state observer (ESO) for estimating uncertainties is discussed in this paper. The scope of the disturbances that can be observed by LESO with bounded observing errors is given. The observing errors for several typical disturbances-constant disturbance, sine disturbance, ramp disturbance, and square wave disturbance are ...

Discrete implementation and generalization of the extended state observer
2006 American Control Conference, 2006A brief review of developments in disturbance observers, leading up to the extended state observer (ESO), is first presented. Various digital implementations of the ESO are investigated and compared. The realization in current discrete estimator form evidently helps to maintain stable operation at low sampling rates.

Optimal fast tracking observer bandwidth of the linear extended state observer
International Journal of Control, 2007In current industrial control applications, the proportional + integral + derivative (PID) control is still used as the leading tool, but constructing controller requires precise mathematical model of plant, and tuning the parameters of controllers is not simple to implement.
