Sensorless Control of Dual Three-Phase IPMSM Based on Frequency Adaptive Linear Extended State Observer [PDF]

open access: yesIEEE 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, 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.

Optimal fast tracking observer bandwidth of the linear extended state observer

International Journal of Control, 2007
In 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.

Extended State Observer Based on ADRC of Linear System with Incipient Fault

International Journal of Control, Automation and Systems, 2019
Owing 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.

Error Analysis of ADRC Linear Extended State Observer for the System with Measurement Noise

open access: yesIFAC-PapersOnLine, 2020
Abstract The Active Disturbance Rejection Control (ADRC) method, which is not dependent upon the accurate system model and has strong robustness for adjusting to disturbances, is widely used in many fields. As the core of the ADRC method, the performance of the Extended State Observer (ESO) is of great importance to the controller.

Comparative analysis of linear and non-linear extended state observer with application to motion control

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 ...

Extended State Observer-Based Predictive Speed Control for Permanent Magnet Linear Synchronous Motor

open access: yesProcesses, 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).

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), 2017
Trajectory 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

An Enhanced Linear Extended State Observer Based Sensorless Control for PMSM Drives

2021 IEEE Applied Power Electronics Conference and Exposition (APEC), 2021
Sliding-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
