Development of a Four-Switch Buck-Boost Converter: Operation Modes, Control and Experimental Results
(Institute of Electrical and Electronics Engineers, 2019-11)
This paper presents the development and practical implementation of a four-switch buck-boost converter for variable input voltage. The circuit operates in buck or boost mode when the input values are higher or lower than ...
Optimal mean-variance control for discrete-time linear systems with Markovian jumps and multiplicative noises
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-02)
In this paper, we consider the stochastic optimal control problem of discrete-time linear systems subject to Markov jumps and multiplicative noises under two criteria. The first one is an unconstrained mean-variance trade-off ...
Discrete-time mean variance optimal control of linear systems with Markovian jumps and multiplicative noise
(TAYLOR & FRANCIS LTD, 2009)
In this article, we consider the stochastic optimal control problem of discrete-time linear systems subject to Markov jumps and multiplicative noise under three kinds of performance criterions related to the final value ...
On controller-driven varying-sampling-rate stabilization via Lie-algebraic solvability
(Elsevier, 2013-01)
Control systems involving shared communications networks are becoming ubiquitous. The inclusion of a communications network within a feedback loop imposes new control challenges. We consider a setting where a centralized ...
Generalized Coupled Algebraic Riccati Equations for Discrete-time Markov Jump with Multiplicative Noise Systems
(LAVOISIER, 2008)
In this paper we consider the existence of the maximal and mean square stabilizing solutions for a set of generalized coupled algebraic Riccati equations (GCARE for short) associated to the infinite-horizon stochastic ...
Desenvolvimento de um sistema de controle e supervisão de inversor para turbinas eólicas
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2017-01-20)
The worldwide interest in renewable energy has increased, with a large emphasis on wind energy. In this sense, this work presents the supervision and control of an inverter for wind turbines. It uses a three-phase PWM ...
