2016 24th Mediterranean Conference on Control and Automation (MED), 2016 In this paper, two approaches for model following control in the presence of uncertainties are compared. Specifically, the so-called command governor framework, originally developed as an augmentation to adaptive control, and a modified linear extended state observer are evaluated.

Sensorless Control of Dual Three-Phase IPMSM Based on Frequency Adaptive Linear Extended State Observer [PDF]
IEEE Transactions on Power Electronics, 2023 The sensorless control of interior permanent magnet synchronous motor (IPMSM) based on the conventional linear extended state observer (LESO) does not have sufficient capability to eliminate the steady-state position estimation error. To solve this issue,

On Convergence of the Linear Extended State Observer
IEEE International Symposium on Intelligent Control, 2006Motivated 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.

Optimal fast tracking observer bandwidth of the linear extended state observer
International Journal of Control, 2007In current industrial control applications, the proportional + integral + derivative (PID) control is still used as the leading tool, but constructing controller requires precise mathematical model of plant, and tuning the parameters of controllers is not simple to implement.

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.
