A New Extended State Observer

2021 4th International Conference on Information Systems and Computer Aided Education, 2021
A new extended state observer is proposed in this paper. The internal and external disturbances acting on the nonlinear system in the actual operating environment are reduced to "unknown disturbances". State variables and extended state variables in system are estimated and compensated in real time with input and output data.

A novel fuzzy extended state observer

ISA Transactions, 2020
In designing the extended state observer (ESO), one of the most challenging issues is its performance improvement. In this paper, a simple fuzzy system is proposed to improve the performance of ESO and changes this observer into fuzzy extended state observer (FESO). This FESO is an intelligent linear form of the ESO.

A novel extended state observer

ISA Transactions, 2015
A 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

Event-Triggered Extended State Observer

2021
Based 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.

Toward Event-Triggered Extended State Observer

IEEE Transactions on Automatic Control, 2018
In this note, we consider event-triggered extended state observer (ET-ESO) design for a continuous-time nonlinear system with uncertainty and disturbance. Since the convergence of the ET-ESO depends on the design of the triggering condition directly, the goal is to design a realizable triggering condition not relying on the state of the plant.
