Improvement of disturbance suppression based on disturbance observer

9th IEEE International Workshop on Advanced Motion Control, 2006., 2006
This research focuses on improvement of disturbance suppression even under existence of observation noise. Disturbance observer is an effective tool to estimate and compensate disturbance. There is a problem, however, that it cannot accomplish desired disturbance suppression when a large observation noise exists.

Fault diagnosis with disturbance rejection performance based on disturbance observer

Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009
In this paper, a new fault diagnosis approach presented for a class of non-linear systems with external urbances. The unknown disturbances are supposed to be rated by an exogenous system, where some classical assumptions on disturbances can be removed.

Noise Reduction Disturbance Observer for Disturbance Attenuation and Noise Suppression

IEEE Transactions on Industrial Electronics, 2017
In most research works on the disturbance observer (DOB)-based controller, stability conditions are only sufficient and not effective for handling large uncertainties. To deal with large uncertainties, a necessary and sufficient condition for robust stability has been recently provided by utilizing a novel design technique for the Q -filter. Although

A survey of state and disturbance observers for practitioners

2006 American Control Conference, 2006
This paper gives a unified and historical review of observer design for the benefit of practitioners. It is unified in the sense that all observers are examined in terms of: 1) the assumed dynamic structure of the plant; 2) the required information, including the input signals and modeling information of the plant; and 3) the implementation equation of

Integral action — A disturbance observer approach

2003 European Control Conference (ECC), 2003
Integral action is required in many controllers in order to solve real world problems. Modeling errors and disturbances are examples of issues that can be dealt with by using controllers with integral action. This paper explores the use of disturbance observers to introduce integral action into an output feedback controller. In particular, the proposed

An observer with controller to detect and reject disturbances

International Journal of Control, 2013
In this paper, a novel states observer is designed. This observer not only estimates the states, but also detects the disturbances by creating estimated signals. Then, both the observed states and detected disturbances are used in a control law to reject the disturbances, avoiding the requirement to know the states and disturbances.

Fuzzy controllers with/without disturbance observer

2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016
A so-called lumped disturbance is considered in the T-S fuzzy model of the system to be controlled. Under the circumstances, this paper proposes two controllers, in which one is designed only on the basis of the control system stability, and the other is designed on the basis of both the control system stability and a proposed disturbance observer ...
