Control Schemes for Disturbance Rejection: A Case Study
(Planta Piloto de Ingeniería Química, 2001-03)
Chemical processes are usually designed to work under a specified set of conditions; therefore the first goal of a regulatory control scheme is to keep the controlled variable at or near these conditions in the presence ...
Finite-Set Model Predictive Current Control of Induction Motors by Direct Use of Total Disturbance
(Institute of Electrical and Electronics Engineers Inc., 2021)
Disturbance rejection strategies are very useful for the robustness improvement of the predictive control method. But they can only be used in the modulated-based predictive control methods such as continuous set model ...
Fractional adaptive systems in the presence of bounded disturbances and parameter variations
(Wiley, 2017)
This paper presents the analysis of fractional adaptive systems in the presence of bounded disturbances and parameter variations. Fractional adaptive systems are analyzed using the error model approach, to give generality ...
Harmonic Disturbance Rejection Control for Magnetic Field Compensation Applications
(Planta Piloto de Ingeniería Química, 2013-08)
A simple control strategy was studied for harmonic disturbance rejection in magnetic field compensation systems for low-field magnetic resonance techniques. The strategy is based on the simultaneous action of a conventional ...
Performance criteria based on nonlinear measures
(Pergamon-Elsevier Science Ltd, 2004-08)
To impart disturbance rejection properties is an important goal in the design of an appropriate process control structure. In a multivariable control system, the effectiveness of disturbance rejection can depend strongly ...
Active Disturbance Rejection Control of Horizontal-Axis Wind Turbines
(2017-03-22)
Abstract. Wind turbines are complex nonlinear machines whose main objective is to convert the wind energy into electric power. These systems work in two main operating regions. In region 2, the energy captured must be ...
Rejection of periodic disturbances using MRAC with minimal controller synthesis
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2016-09-06)
The tracking/rejection of periodic disturbances in linear systems is achievable via internal model principle-based techniques, such as repetitive control. However, when the frequency of the signal to track/reject is uncertain ...
Controle por modos deslizantes e observador de distúrbios aplicados ao motor síncrono de ímãs permanentes
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-08-20)
This master thesis proposes a current control technique based on sliding mode strategy
and disturbance observer for high-performance drive applied to permanent magnet
synchronous motors and can be extended to other ...
Rejection of periodic disturbances using MRAC with minimal controller synthesis
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2018)
Predictive feedback control: An alternative to proportional-integral-derivative control
(Professional Engineering Publishing Ltd, 2009-07)
Even though employed widely in industrial practice, the popular proportional?integral?derivative (PID) controller has weaknesses that limit its achievable performance. In this paper, an alternative control scheme that ...
