Improving the stability conditions of TS fuzzy systems with fuzzy Lyapunov functions
In this paper, the fuzzy Lyapunov function approach is considered for stabilizing continuous-time Takagi-Sugeno fuzzy systems. Previous linear matrix inequality (LMI) stability conditions are relaxed by exploring further ...
Modelagem matemática por meio de Sistemas Fuzzy: um Instrumento para avaliação de autismo
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Matemática (PROFMAT)Câmpus Sorocaba, 2019-02-21)
In this work, concepts, definitions and theorems about Fuzzy Logic and Systems Based on Fuzzy Rules were presented. We used these systems to develop a mathematical model for diagnosing autism based on the CARS-BR scale: ...

Tratamento de imprecisão na geração de árvores de decisão
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciência da ComputaçãoCâmpus São Carlos, 2016-03-03)
Inductive Decision Trees (DT) are mechanisms based on the symbolic paradigm of machine learning which main characteristics are easy interpretability and low computational cost. Though they are widely used, the DTs can ...
A fuzzy Lyapunov function approach for stabilization and control of switched TS fuzzy systems
In this work, sufficient conditions for the existence of switching laws for stabilizing switched TS fuzzy systems via a fuzzy Lyapunov function are proposed. The conditions are found by exploring properties of the membership ...
An extension of the invariance principle for switched T-S fuzzy systems
(IEEEEuropean Control Association (EUCA)Zurich, 2013)
In this work, we propose an extension of the invariance principle for switched T-S fuzzy systems using an auxiliary function V for the convex combination of the subsystems which applies to unstable subsystems. The ...
Estabilização de sistemas fuzzy T-S incertos usando realimenta̧ão derivativa
In some practical problems, for instance, in the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Thus, a method for state-derivative feedback design ...
