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 ...

AbstractIn this paper, a trajectory linearization control based control law using a linear extended state observer (LESO) is proposed for the output tracking problem of a nonlinear system with uncertainties. First, based on the tracking error dynamics derived by Taylor expansion for the original nonlinear system along the desired trajectory, a feedback

International Conference for Convergence for Technology-2014, 2014
The design of observer for estimating states, disturbances, and uncertainty in plant dynamics is an important step for achieving high performance model based control schemes. This paper gives the estimation of states and lumped uncertainty by using extended state observer (ESO) and feedback linearization technique; moreover the question raised in this ...

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 ...

Extended State Observer Based on ADRC of Linear System with Incipient Fault
International Journal of Control, Automation and Systems, 2019Owing to the fact that it is difficult to find the incipient fault and it is hard to deal with the disturbance, an extended state observer (ESO), which is based on the linear time invariant system is designed and analyzed. This method can effectively separate incipient fault as a new state variable from the disturbance.

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.

Backstepping sliding-mode control for missile attitude using a linear extended state observer
Proceedings of 2014 IEEE Chinese Guidance, Navigation and Control Conference, 2014On the basis of nonlinear dynamic inversion theory, a novel scheme combining sliding-mode control and backstepping is proposed for missile attitude control. In order to handle matched and unmatched uncertainties caused by unmodeled dynamics and variations of aerodynamic coefficients, a linear extended state observer (LESO) is introduced to estimate the

Linear motor tracking control based on adaptive robust control and extended state observer
2017 IEEE International Conference on Cybernetics and Intelligent Systems (CIS) and IEEE Conference on Robotics, Automation and Mechatronics (RAM), 2017Trajectory tracking control for linear oscillating motor is critical to improve the performance of linear electro-hydrostatic actuator (LEHA). However, both structured uncertainties (i.e., parametric uncertainties) and unstructured uncertainties (i.e., unmodeled dynamics, external disturbances, nonlinear friction) exist in LEHA may severely deteriorate

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.
