Purpose Trajectory tracking error of robotic manipulator has limited its applications in trajectory tracking control systems. This paper aims to improve the trajectory tracking accuracy of robotic manipulator, so a linear-extended-state-observer (LESO)-based prescribed performance controller is proposed.

Formation control for nonlinear multi-agent systems with linear extended state observer
IEEE/CAA Journal of Automatica Sinica, 2014This paper investigates the formation control problem for nonlinear multi-agent systems with a virtual leader. A distributed formation control strategy based on linear extended state observer (LESO) is proposed under the hypothesis that velocity of the agent's neighbors could not be measured.

Transactions of the Institute of Measurement and Control, 2021
This paper describes a predictive extended state observer-based robust control for uncertain process control applications. The technique discussed in the article uses the extended state observer (ESO) that can estimate the dynamics of the system as well as total disturbance encountered in the system.

Model-assisted Linear Extended State Observer for Opto-Electronic Stabilized Platform
2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC), 2019In this paper, a control strategy with a model-assisted linear extended state observer (MLESO) is proposed to enhance the disturbance suppression performance for Opto-Electronic stabilized platform. First, we incorporate known model information which can be identified from the open loop frequency response of controlled plant in the framework of the ...

Extended State Observer for Sensorless Single Phase Stirling Linear Generator Drives
Applied Mechanics and Materials, 2013The extended state observer (ESO) was applied in the sensorless single phase Stirling linear generator drives in this paper. The structure of the linear generator was introduced and mathematical model was built. To detect the mover position in the condition of position sensorless, the back-EMF ESO was deduced to calculate the position.

Estimation of transient state of multi-machine power system by extended linear observer
IEEE Transactions on Power Apparatus and Systems, 1977The development of extended linear observer estimating the transient state of power system has been made previously [5], using one-machine infinite bus system. In this paper, the application of this estimation technique to the multi-machine system is investigated.

Capability Analysis of Linear Extended State Observer Under Model Mismatch for LADRC control
2021 40th Chinese Control Conference (CCC), 2021The Linear Extended State Observer (LESO) with model mismatch for Linear Active Disturbance Rejection Control (LADRC) is investigated in this paper, which is different from the existed results that only consider the unknown disturbances. Not only the uncertain disturbances in system are considered, but the model mismatch between the observer and the ...

Model Predictive Control of Two-Stage Rectifier Based on Linear Extended State Observer
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021This paper presents a model predictive control (MPC) method of two-stage rectifier based on linear extended state observer (LESO). The control performance of conventional MPC is easy to be affected under parameter mismatches and external perturbation condition.

Robust Decoupling Control Based on Linear Extended State Observers for Grid-Forming Inverter
2024 IEEE 34th Australasian Universities Power Engineering Conference (AUPEC)Grid-forming inverters (GFMIs) based on virtual synchronous generators (VSGs) have emerged as a promising solution for providing inertia and enhancing renewable system stability. However, the inherent power coupling caused by the low reactance-to-resistance ratio in low-voltage networks negatively impacts the control performance of VSGs.

Tracking of stribeck friction based on second-order linear extended state observer
2016 Chinese Control and Decision Conference (CCDC), 2016To deal with the problem of observing or tracking for discontinuous signal, a kind of second order linear extended state observer (LESO) algorithm is proposed. By ESO estimating the uncertain disturbance, a simple second-order linear ESO with less tunable parameters was designed in the absence of dynamic model, and the method of discrete time ...
