Método de controle Sensorless para motores síncronos de imãs permanentes
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-11-29)
This paper presents the study and development of a sensorless control method for the Permanent Magnet Synchronous Motor (PMSM) based on the estimation of back Electromotive Force (back-EMF). A vector control method is ...
Comparative study of inversion-based and observer-based approaches for fault diagnosis in DC-DC converters
(2017-07-07)
Recently, model-based approaches have been proposed for fault diagnosis as an emerging alternative to traditional techniques. Particularly, the inversion-and observer-based were proposed for fault diagnosis as successful ...
Predictive Torque Control of Induction Motor Based on a Robust Integral Sliding Mode Observer
(2023-03-01)
The parameter estimators and the disturbance observers are two widely used methods for the robustness improvement of the model predictive control schemes. This article presents a hybrid solution to improve the robustness ...
Sensorless control of doubly-fed induction generators using a rotor-current-based mras observer
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Projeto e análise de observadores para o controle sensorless de máquinas BLDC aplicadas na tração de veículos elétricos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-02-25)
This master’s thesis presents a sensorless control of a BLDC machine for the traction
of electric vehicles. Due to its characteristics, the BLDC is an excellent candidate
for such application. In this context, the safety ...
Observability criteria for impulsive control systems with applications to biomedical engineering processes
(Elsevier, 2015-03)
One of the fundamental properties of the impulsive systems is analyzed: observability. Algebraic criteria for testing this property are obtained for the nonlinear case, considering continuous and discrete outputs. For this ...
A high gain nonlinear observer: Application to the control of an unstable nonlinear process
(Pergamon-Elsevier Science Ltd, 2004-08)
State estimation has become an important area of research in the field of process engineering. This is because there are many applications that demand the knowledge of many of the state variables, if not all of them. Among ...
Controle escalar sensorless para sistemas de conversão de energia eólica com gerador síncrono de ímãs permanentes
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-08-21)
This master thesis proposes a control method of scalar direct torque control and
a technique of current control to maximize the aerodynamic efficiency of wind energy
conversion systems (WECS) using permanent magnets ...
Weak detectability and the linear-quadratic control problem of discrete-time Markov jump linear systems
(Taylor & Francis LtdAbingdonInglaterra, 2002)
Inerter-added transmissibility to control base displacement in isolated structures
(Springer Science and Business Media Deutschland GmbH, 2022-01-15)
his paper proposes a Lean Green model for increasing profitability in small and medium-sized businesses operating within the plastics sector. This model will use the 5S methodology, KanBan for inventory control and TPM to ...
