Generalized-Extended-State-Observer and Equivalent-Input-Disturbance Methods for Active Disturbance Rejection: Deep Observation and Comparison

IEEE/CAA Journal of Automatica Sinica, 2023
Active disturbance-rejection methods are effective in estimating and rejecting disturbances in both transient and steady-state responses. This paper presents a deep observation on and a comparison between two of those methods: the generalized extended ...

Generalized Active Disturbance Rejection With Reduced-Order Vector Resonant Control for PMSM Current Disturbances Suppression

IEEE transactions on power electronics, 2023
A control strategy that combines a novel reduced-order vector resonant controller and a generalized active disturbance rejection control (ROVR-GADRC) is proposed in this article to suppress the current disturbances containing periodic harmonics of a ...

A Disturbance Decoupling Generalized Proportional–Integral Observer Design for Robust Sensor Fault Detection

IEEE transactions on industrial electronics (1982. Print), 2023
This article presents a novel disturbance decoupling generalized proportional–integral observer (DD-GPIO) for the early detection of sensor faults in dynamic systems subject to external semistationary periodic disturbances.

Iterative parameter identification algorithms for the generalized time‐varying system with a measurable disturbance vector

International Journal of Robust and Nonlinear Control, 2021
This article deals with the parameter identification of the generalized time‐varying systems. The time‐varying parameter vector can be expressed as a coefficient matrix multiplied by a measurable disturbance vector, the common identification methods ...

Disturbance-generated competitive coexistence

2023
AbstractExplaining how competing species coexist remains a challenge in ecology. A major hypothesis is that disturbance opens up the opportunity for types with different “life history” strategies to coexist, allowing types better at getting to and using recently disturbed patches to coexist with better competitor types.

Disturbance observers for general exogenous disturbances

2019 IEEE International Conference on Mechatronics and Automation (ICMA), 2019
We examine a parameterization of linear disturbance observers for general exogenous disturbances. Using the states and inputs of the system as variables, we got an parameterization of linear disturbance observers for general exogenous disturbances in frequency domain formulation.

New results on the robust stability of control systems with a generalized disturbance observer

Asian journal of control, 2019
A generalized disturbance observer‐based (GDOB) control system and its robust stability are studied in this paper. One feature of this new GDOB scheme is that an inverse of the nominal plant in the standard DOB is no longer required.
