A Triangulation Approach to Asymptotically Exact Conditions for Fuzzy Summations
Kruszewski, A.; Sala, Antonio; Guerra, T. M.; Ariño Latorre, Carlos Vicente 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 ... -
Asymptotically exact stabilisation for constrained discrete Takagi–Sugeno systems via set-invariance
Ariño Latorre, Carlos Vicente; Sala, Antonio; Pérez, Emilio; Bedate Boluda, Fernando; Querol, Andrés Elsevier (2016-10-12)Given a Takagi–Sugeno (TS) system, this paper proposes a novel methodology to obtain the state feedback controller guar- anteeing, asymptotically as a Polya-related complexity parameter grows, t ... -
Closed-form estimates of the domain of attraction for nonlinear systems via fuzzy-polynomial models
Pitarch Pérez, José Luis; Sala, Antonio; Ariño Latorre, Carlos Vicente 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 ... -

Ariño Latorre, Carlos Vicente; Pitarch Pérez, José Luis; Sala, Antonio 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 ... -
Estimación del dominio de atracción de sistemas no lineales mediante modelos borrosos polinomiale
Ariño Latorre, Carlos Vicente; Bedate Boluda, Fernando; Pitarch Pérez, José Luis; Sala, Antonio Elservier (2012-04)Many approaches in fuzzy systems literature express LMI con- ditions for a Takagi-Sugeno model and finish the problem once those conditions are feasible. However, studying the obtained re- gion of attraction and its ... -
Explicit Predictive Control with Non-Convex Polyhedral Constraints
Pérez, Emilio; Ariño Latorre, Carlos Vicente; Blasco Ferragud, F. Xavier; Martínez Martí, Miguel Ángel Elsevier (2012-02)This paper proposes an explicit solution to the model predictive control of linear systems subject to non-convex polyhedral constraints. These constraints are modeled as the union of a finite number of convex polyhedra. ... -
Extensions to “Stability Analysis of Fuzzy Control Systems Subject to Uncertain Grades of Membership”
Ariño Latorre, Carlos Vicente; Sala, Antonio Institute of Electrical and Electronics Engineer (New York) (2008)In the December 2005 issue of this journal, Lam and Leung proposed stability results for fuzzy control systems where the membership functions in the controller were not the same as those from the process one, but some ... -

Polynomial Fuzzy Models for Nonlinear Control: A Taylor Series Approach
Sala, Antonio; Ariño Latorre, Carlos Vicente 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 ... -

Relaxed Stability and Performance LMI Conditions for Takagi-Sugeno Fuzzy Systems With Polynomial Constraints on Membership Function Shapes
Ariño Latorre, Carlos Vicente; Sala, Antonio Institute of Electrical and Electronics Engineers (2008)Most linear matrix inequality (LMI) fuzzy control results in literature are valid for any membership function, i.e., independent of the actual membership shape. Hence, they are conservative (with respect to other nonlinear ... -
