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.

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.

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.

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 ...

Design of fuzzy controller with linear extended state observer for magnetic suspension bearings
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014A high performance controller for magnetic suspension bearings is investigated. To improve the robustness of the controller and the suspension accuracy of the system, a fuzzy controller is designed using variable bandwidth triangle membership function. Considering the poor static-state performance of traditional fuzzy controllers, an additional linear ...

A linear extended state observer (LESO) based fuzzy fault tolerant control (FTC) scheme is designed for an over-actuated autonomous underwater vehicle (AUV) to address the faults of actuators. In this scheme, both the faults of the actuators and other immeasurable disturbances are lumped into a generalized total disturbance, which is then estimated by ...
