Novel Augmented Extended State Observer Design

2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics, 2015
This 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

Extended state observer for MIMO nonlinear systems with stochastic uncertainties

International Journal of Control, 2018
ABSTRACTIn this paper, both linear extended state observer (ESO) and nonlinear ESO with homogeneous weighted functions are proposed for a class of multi-input multi-output (MIMO) nonlinear systems ...

On stability of sampled-data extended state observer for networked systems

2017 11th Asian Control Conference (ASCC), 2017
The 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, 2016
This 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, 2014
Structured 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

Survey on methods of increasing the efficiency of extended state disturbance observers

ISA Transactions, 2015
This survey presents various methods of improving the overall estimation quality in the class of extended state observers (ESO), which estimate not only the conventional states of the system, but the acting disturbance as well. This type of observers is crucial in forming the active disturbance rejection control structure (ADRC), where the precision of
