A Super-Twisting Extended State Observer for Nonlinear Systems [PDF]
Mathematics, 2022 Disturbances and uncertainties are the main concerns in control systems. To obtain this information in real time, the extended state observer is proposed as the core of the active disturbance rejection control.

PD-Based Optimal ADRC with Improved Linear Extended State Observer [PDF]
Entropy, 2021 Taking dead-zone nonlinearlity and external disturbances into account, an active disturbance rejection optimal controller based on a proportional-derivative (PD) control law is proposed by connecting the proportional-integral-derivative (PID) control ...

Non-Recursive Fixed-Time Convergence Observer and Extended State Observer
IEEE Access, 2018 In this paper, non-recursive fixed-time convergence (FxTC) observers were proposed to deal with missions, such as state estimation and tracking differentiation. The observers were designed based on the time-scale paradigm, such that the parameters tuning

Active vibration suppression for rolling mills vibration based on extended state observer and parameter identification [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2020 Rolling mills vibration is a key factor that hinders the production of thin-strip steel. Currently, vibration is mainly suppressed by adjusting rolling mill parameters which is not a common approach.

Observation of Robust Zero-Energy Extended States
Physical Review Applied, 2023 Topological edge states arise at the interface of two topologically-distinct structures and have two distinct features: they are localized and robust against symmetry protecting disorder. On the other hand, conventional transport in one dimension is associated with extended states, which typically do not have topological robustness.
