An Enhanced Linear Extended State Observer Based Sensorless Control for PMSM Drives
2021 IEEE Applied Power Electronics Conference and Exposition (APEC), 2021Sliding-mode observer (SMO) based sensorless field-oriented control (FOC) methods have been widely employed for permanent-magnet synchronous motor (PMSM) drives in medium-speed and high-speed electrical vehicles. However, these methods have two main problems, i.e., phase delay and speed chattering problems. Moreover, the position estimation performance

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

Industrial Robot: the international journal of robotics research and application, 2021
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.

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 ...

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.

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.
