Polynomial Fuzzy Models for Nonlinear Control: A Taylor Series Approach
(Institute of Electrical and Electronics Engineers (IEEE), 2009-12)
Classical Takagi-Sugeno (T-S) fuzzy models are formed by convex combinations of linear consequent local models. Such fuzzy models can be obtained from nonlinear first-principle equations by the well-known sector-nonlinearity ...
Closed-form estimates of the domain of attraction for nonlinear systems via fuzzy-polynomial models
(Institute of Electrical and Electronics Engineers (IEEE), 2014-04)
In this work, the domain of attraction of the origin of
a nonlinear system is estimated in closed-form via level sets with
polynomial boundary, iteratively computed. In particular, the
domain of attraction is expanded ...
Minimal Controllable Set for Takagi-Sugeno Fuzzy Systems with disturbances
(ElsevierIFAC (International Federation of Automatic Control), 2019-10-29)
In this paper, an approximation of the smallest set (in a given norm) to which the state of a system can be steered (and kept inside once reached) is provided, when bounded disturbances are present. A non-LMI geometric ...
Sampled-data gain scheduling of continuous LTV plants
(Elsevier, 2009)
This paper discusses the design of gain-scheduled sampled-data controllers for continuous-time polytopic linear parameter-varying systems. The scheduling variables are assumed to be available only at the sampling instants, ...
Guaranteed cost control analysis and iterative design for constrained Takagi-Sugeno systems
(Elsevier, 2010)
This paper presents a novel control design technique in order to obtain a guaranteed cost fuzzy controller subject to constraints on the input channel. This guaranteed cost control law is obtained via multi-parametric ...
A Triangulation Approach to Asymptotically Exact Conditions for Fuzzy Summations
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Many Takagi-Sugeno (T-S) fuzzy control-synthesis problems in the literature are expressed as the problem of finding decision variables in a double convex sum (fuzzy summation) of positive definite matrices. Matricespsila ...
Polytopic invariant and contractive sets for closed-loop discrete fuzzy systems
(Elsevier, 2014)
In this work a procedure for obtaining polytopic λ-contractive sets for Takagi-Sugeno fuzzy systems is presented, adapting well-known algorithms from literature on discrete-time linear difference inclusions (LDI) to ...
Estabilidad de sistemas Takagi-Sugeno bajo perturbaciones persistentes:estimación de conjuntos inescapables
(Elsevier, 2015)
El presente trabajo analiza el comportamiento de sistemas borrosos Takagi-Sugeno ante perturbaciones persistentes (caracterizadas bien por cotas conocidas de amplitud o de potencia en media cuadrática). El análisis se ...
Diseño del control de un convertidor DC-DC de dos etapas con un algoritmo genético
(Publicaciones de Ingeniería, Escuela Técnica Superior de Ingeniería, 2015)
Este art ́ıculo introduce la estructura y el disen ̃o del control de un convertidor DC–DC bidireccional que sirve para gestionar los flujos de energ ́ıa en el lado de continua de un filtro activo que asume el rol de mas- ...
