An Extended State Observer Based on Tracking Differentiator
2006 Chinese Control Conference, 2006A series tracking differentiator (TD) that is in the form of observer is used as substitute for the extended state observer (ESO) in active disturbance rejection controller (ADRC). This improved ESO independently of original system model is not only simple for the parameters tuning, but also good for filter performance. The simulation results show that

A New Switching Nonlinear Extended State Observer
2019 Chinese Control And Decision Conference (CCDC), 2019To improve the observation accuracy and shorten the transient time simultaneously, in this paper, we propose a new nonlinear extended state observer (ESO) by using a switching strategy. The convergence of the proposed ESO is proved with explicit error estimation. The effectiveness of the proposed switched nonlinear ESO is demonstrated through numerical

Novel Augmented Extended State Observer Design
2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics, 2015This paper proposes the construction method and validation of novel augmented extended state observer (NAESO). First, based on singular perturbation technique, the general formulation and structure of NAESO is derived. Based on which, the linear NAESO version is given. The merits of the presented NAESO include ease of parameter selection and sufficient

2017 American Control Conference (ACC), 2017
In this paper, a generalized extended state observer (GESO) is proposed to accurately observe supercapacitor's state of charge (SOC) by counteracting the modeling deviation and disturbances. With the consideration of dynamic modeling uncertainty and disturbances, a nonlinear mathematical model is established based on the three branch equivalent circuit

On stability of sampled-data extended state observer for networked systems
2017 11th Asian Control Conference (ASCC), 2017The problem of sampled-data state observation is considered in this work. A nonlinear continuous-time system with internal uncertainty and external disturbance is introduced, for which the sampled-data observation problem based on an extended state observer is formulated.

Extended State Observer based control for coaxial-rotor UAV
ISA Transactions, 2016This paper considers the problem of controlling the position and the orientation of a Coaxial-Rotor Unmanned Aerial Vehicle -CRUAV- despite unknown aerodynamic efforts. A hierarchical flight controller is designed, allowing the trajectory tracking and the stabilization of the vehicle.

Adaptive Robust Control of DC Motors With Extended State Observer
IEEE Transactions on Industrial Electronics, 2014Structured and unstructured uncertainties always exist in physical servo systems and degrade their tracking accuracy. In this paper, a practical method named adaptive robust control with extended state observer (ESO) is synthesized for high-accuracy motion control of a dc motor. The proposed controller accounts for not only the structured uncertainties
