On the fixed poles for disturbance rejection

Automatica, 1997
We propose a geometric characterization of the fixed poles for the disturbance-rejection problem by static state feedback and, in the particular case when the system is controllable, a structural characterization in terms of finite invariant zeros of certain open-loop subsystems.

Disturbance rejection of switched systems

Proceedings of the 2004 American Control Conference, 2004
In this paper, we investigate the disturbance rejection of switched systems with unit-amplitude disturbance input by designing a state-dependent switching law. All the results in this paper are expressed in terms of LMIs, which can be easily tested with efficient LMI algorithm.

Disturbance rejection for nonlinear systems

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
Tracking or rejection of unknown exogenous signals with known generating dynamics is of major concern in feedback control design. Linear feedback control based on the internal model principle achieves asymptotic performance for linear systems with linear exogenous signal dynamics.

Disturbance rejection for space-based manipulators

Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 1999
This paper describes the implementation of a disturbance rejection controller for a 6-DOF PUMA manipulator mounted on a 3-DOF platform. A control algorithm is designed to track the desired position and attitude of the end-effector in inertial space, subject to unknown disturbances in the platform axes.

On perfect disturbance rejection

Proceedings of 32nd IEEE Conference on Decision and Control, 2002
A new observer-based approach to perfect disturbance rejection in linear continuous systems is introduced. A technique of continuous deadbeat observation is exploited to estimate the disturbance signal described by a known dynamic model. A realization condition in the form of linear algebraic equations is derived.

Robust disturbance rejection

Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002
The problem of robust asymptotic disturbance rejection for systems involving parametric uncertainties is studied. A design method is proposed that is based on polynomial techniques. Various uncertainty structures are considered including single and multiple parameters as well as affine, polynomic and even non-polynomic cases.

Decoupling and disturbance rejection

IEEE Transactions on Automatic Control, 1975
For the linear multivariable system \dot{x} = Ax + Bu + Er, z_{i} = D_{i}x(i \in k), x \in X , with disturbance \Gamma(\cdot) , it is shown that the decoupling problem and disturbance rejection problem are simultaneously solvable, so as to yield a stable closed-loop system, if and only if Im(E)\subset V_{g}^{*} and R_{i}^{*} + \ker D_{i} = X, i \in k .

Disturbance rejection performance limit for a class of disturbance signals

2015 54th IEEE Conference on Decision and Control (CDC), 2015
This paper deals with analysis of fundamental limitations in tracking control problems. In the existing results, the fundamental limitations are analyzed based on detailed assumptions of reference signals such as the step and the trigonometrical signals and so on. On the other hand, we define a class of reference signals in a general manner.

Adaptive disturbance rejection

[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 2002
Using averaging analysis a novel direct adaptive algorithm applied to a linear plant is analyzed. The prior knowledge includes a nominal model and a stabilizing controller for the plant. It is shown that the stabilizing controller can be augmented with an adaptive controller solely aimed at disturbance rejection/trajectory following. The overall scheme

Synthesized Disturbance Observer for Vehicle Lateral Disturbance Rejection

2018 Annual American Control Conference (ACC), 2018
Fast disturbance detection and compensation play an important role in vehicle steering control system. Disturbance observer (DOB) is an effective technique to compensate for the disturbance. However, the design procedure of the DOB requires a stable inverse of the plant and an additional $Q$ filter to guarantee the stability and the robustness to ...
