Disturbance rejection of time-delay systems

International Journal of Systems Science, 1993
The disturbance decoupling problem is addressed for a class of time-delay nonlinear systems, including linear systems as a particular case. Conditions are given for having causal control laws, and a methodology is proposed for designing the corresponding controllers. An example illustrates the design procedure.

Deterministic Disturbance Rejection in Linear Identification

Journal of Dynamic Systems, Measurement, and Control, 1977
Adverse effects of deterministic disturbances in linear identification are pointed out. The deterministic disturbance rejector (DDR) is introduced to remove such effects in discrete-time series-parallel and parallel identification schemes for single-input, single-output systems.

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.

Disturbance Tolerance and Rejection

2017
Linear systems in the presence of actuator saturation and exogenous disturbances have been well studied in the literature. For input additive disturbances, very strong results have been established (see, for example, [16, 73, 75]). In [75], it was established that, for a neutrally stable system, finite gain \(\mathcal{L}_{p}\) stability can be achieved

Closing Chapter: Disturbance Rejection

2014
A survey of the recent literature concerning plasma-based processes reveals that direct feedback of plasma parameters for process control is currently being explored related to plasma-cleaning operations. Feedback from plasma monitoring systems such as in situ Langmuir probes would enable more sophisticated control characteristics such as disturbance ...

Modified disturbance rejection problem

Computers & Structures, 2003
Abstract In this study, vibration control of earthquake-excited structures is treated as a modified disturbance rejection problem with a parameter ξ s first introduced in Pincer procedure and the optimal control policy is derived by using well known Hamilton–Jacobi optimality equation.

Persistent disturbance rejection via static-state feedback

IEEE Transactions on Automatic Control, 1995
Summary: In contrast with \({\mathcal H}_\infty\) and \({\mathcal H}_2\) control theories, the problem of persistent disturbance rejection (\(l^1\) optimal control) leads to dynamic controllers, even when the states of the plant are available for feedback. Using viability theory, it has recently been shown, in a nonconstructive way [\textit{J.

Disturbance prediction based active disturbance rejection control approach

2016 35th Chinese Control Conference (CCC), 2016
Disturbance widely exists in control system. Active disturbance rejection control (ADRC) has been proved to be an efficient way to deal with disturbance and achieves great success in practice. The most important part of ADRC is extended state observer (ESO), which estimates the states of system and total disturbance.

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 ...
