Análise de desempenho de controladores aplicados ao sistema pêndulo invertido
(Universidade Tecnológica Federal do ParanáToledo, 2014-02-24)
The main goal of this paper is to design different topologies of controllers for the inverted pendulum system in order to analyze and compare “their performance”. At first a mathematical modeling of the proposed system ...
On the number of limit cycles in discontinuous piecewise linear differential systems with two pieces separated by a straight line
(Elsevier B.V., 2015-04-01)
In this paper we study the maximum number N of limit cycles that can exhibit a planar piecewise linear differential system formed by two pieces separated by a straight line. More precisely, we prove that this maximum number ...
A comparative study between two relaxed LMI-based fuzzy control designs
(2005-09-01)
A comparative study, with theoretical analysis and digital simulations, of two conditions based on LMI for the quadratic stability of nonlinear continuous-time dynamic systems, described by Takagi-Sugeno fuzzy models, are ...

On an Optimal Linear Control of a Chaotic Non-Ideal Duffing System
(Trans Tech Publications Ltd, 2012-01-01)
In this work, we use a nonlinear control based on Optimal Linear Control. We used as mathematical model a Duffing equation to model a supporting structure for an unbalanced rotating machine with limited power (non-ideal ...
A reducing of a chaotic movement to a periodic orbit, of a micro-electro-mechanical system, by using an optimal linear control design
(Elsevier B.V., 2009-05-01)
This paper analyzes the non-linear dynamics. with a chaotic behavior of a particular microelectro-mechanical system. We used a technique of the optimal linear control for reducing the irregular (chaotic) oscillatory movement ...

On local analysis of oscillations of a non-ideal and non-linear mechanical model
(Kluwer Academic Publ, 2004-08-01)
It is of major importance to consider non-ideal energy sources in engineering problems. They act on an oscillating system and at the same time experience a reciprocal action from the system. Here, a non-ideal system is ...
