Novel Active Disturbance Rejection Control Based on Nested Linear Extended State Observers [PDF]
Applied Sciences, 2020 In this paper, a Novel Active Disturbance Rejection Control (N-ADRC) strategy is proposed that replaces the Linear Extended State Observer (LESO) used in Conventional ADRC (C-ADRC) with a nested LESO.

Robust predictive current control of induction motors based on linear extended state observer [PDF]
Chinese Journal of Electrical Engineering, 2021 Model predictive current control can achieve fast dynamic response and satisfactory steady-state performance for induction motor (IM) drives. However, many motor parameters are required to implement the control algorithm. Consequently, if the motor parameters used in the controller are not accurate, the performance may deteriorate. In this paper, a new

Extended State Observer-Based Predictive Speed Control for Permanent Magnet Linear Synchronous Motor [PDF]
Processes, 2019 Combining the feedback of predictive function control and the feedforward of extended state observer, a composite control strategy is proposed for the permanent magnet linear synchronous motor (PMLSM). The mathematical model of the PMLSM vector control system is established based on the basic structure and operation mechanism of PMLSM.

On Convergence of the Linear Extended State Observer
IEEE International Symposium on Intelligent Control, 2006 Motivated by the gap between theory and practice in control problems, Linear Active Disturbance Rejection Control (LADRC) addresses a set of control problems in the absence of precise mathematical models. LADRC depends on the quick convergence of a unique state observer, known as the extended state observer, proposed by Han.

Novel Active Disturbance Rejection Control Based on Nested Linear Extended State Observers [PDF]
, 2018 In this paper, a Novel Active Disturbance Rejection Control (N-ADRC) strategy is proposed that replaces the Linear Extended state observer (LESO) used in Conventional ADRC (C-ADRC) with a Nested LESO. In the nested LESO, the inner-loop LESO actively estimates and eliminates the generalized disturbance.

A Model-Based Extended State Observer for Discrete-Time Linear Multivariable Systems [PDF]
A model-based extended state observer (MB-ESO) and its variant are proposed for discrete-time linear multivariable systems, where multiple disturbances are defined as an extended state vector in the same manner as in the original formulation of ESO. The variant MB-ESO extends the MB-ESO to address cases where the disturbance gain matrix is non-diagonal.

Modified Extended State Observer Control of Linear Systems
AIAA Guidance, Navigation, and Control Conference, 2016 In this paper, a novel architecture for model following control of uncertain Linear Time Invariant (LTI) systems in case of state feedback is presented. The architecture is based on a Modified Linear Extended State Observer (MLESO), which estimates the disturbance signal that causes the real plant to deviate from the reference model.
