PD-Based Optimal ADRC with Improved Linear Extended State Observer [PDF]
Entropy, 2021 Taking dead-zone nonlinearlity and external disturbances into account, an active disturbance rejection optimal controller based on a proportional-derivative (PD) control law is proposed by connecting the proportional-integral-derivative (PID) control ...

A Super-Twisting Extended State Observer for Nonlinear Systems
Mathematics, 2022 Disturbances and uncertainties are the main concerns in control systems. To obtain this information in real time, the extended state observer is proposed as the core of the active disturbance rejection control.

Non-Recursive Fixed-Time Convergence Observer and Extended State Observer
IEEE Access, 2018 In this paper, non-recursive fixed-time convergence (FxTC) observers were proposed to deal with missions, such as state estimation and tracking differentiation. The observers were designed based on the time-scale paradigm, such that the parameters tuning

A continuous time model for observer-based frequency tracking
Results in Control and Optimization, 2023 Frequency tracking has been the focus of several research works for decades. One common method is to utilize a state observer to dynamically estimate the frequency of the measured signal.

Parameterization of a Novel Nonlinear Estimator for Uncertain SISO Systems with Noise Scenario
Mathematics, 2022 Dynamic observers are commonly used in feedback loops to estimate the system’s states from available control inputs and measured outputs. The presence of measurement noise degrades the performance of the observer and consequently degrades the performance
