Frequency‐shifting‐based algebraic approach to extended state observer design
, 2021 In this paper, a frequency‐shifting‐based (FSB) algebraic approach to the extended state observer (ESO) design is proposed. The proposed algebraic approach provides almost instantaneous convergence toward the exact values of the system states and ...

Extended state observer based fractional order sliding mode control for steer‐by‐wire systems [PDF]
, 2023 In this paper, an extended state observer based fractional-order sliding mode control strategy is studied for vehicle steer-by-wire systems (SBWSs). The parameter perturbation and external interference are considered in the dynamic model of SBWSs.

Estimation and compensation for Lipschitz nonlinear discrete-time systems subjected to unknown measurement delays [PDF]
, 2015 Unknown measurement delays usually degrade system performance, and even damage the system under output feedback control, which motivates us to develop an effective method to attenuate or offset the adverse effect from the measurement delays.
