Linear-Extended-State-Observer Based Pinning Control of Nonlinear Multi-Robots System

Linear Extended State Observer-Based Motion Synchronization Control for Hybrid Actuation System of More Electric Aircraft

Moving towards the more electric aircraft (MEA), a hybrid actuator configuration provides an opportunity to introduce electromechanical actuator (EMA) into primary flight control. In the hybrid actuation system (HAS), an electro-hydraulic servo actuator (EHSA) and an EMA operate on the same control surface. In order to solve force fighting problem in HAS, this paper proposes a novel linear exte...

Sampled-data extended state observer for uncertain nonlinear systems

In this paper, we present a sampled-data nonlinear extended state observer (NLESO) design method for a class of nonlinear systems with uncertainties and discrete time output measurement. To accommodate the inter-sample dynamics, an inter-sample output predictor is employed in the structure of the NLESO to estimate the system output in the sampling intervals, where the prediction is used in the ...

Extended State Observer for Nonlinear Systems with Uncertainty

Abstract: The extended state observer first proposed by Jingqing Han in [J. Q. Han, The extended state observer for a class of uncertain systems, Control and Decision, 10(1)(1995), 85-88] is the main interim loop of active disturbance rejection control that is taking off as a technology after numerous successful applications in engineering. Unfortunately, there is no a rigorous proof of converg...
