A Relational Approach for Complex System Identification
نویسندگان
چکیده
Resumo Este trabalho aborda a questão de identificação de sistemas complexos com o auxílio de lógica nebulosa. Apresentam-se dois métodos numéricos para estimar os parâmetros de modelos relacionais, que são modelos construídos a partir de equações relacionais nebulosas. O primeiro método é baseado na solução de uma sequência de problemas quadráticos com o objetivo de refinar modelos previamente identificados através de outros algoritmos. A partir deste método, obtémse também um algoritmo recursivo adequado a aplicações “online”. Avalia-se o desempenho dos métodos propostos através da modelagem de um sistema dinâmico real.

Fuzzy Relational Matrix-Based Stability Analysis for First-Order Fuzzy Relational Dynamic Systems
In this paper, two sets of sufficient conditions are obtained to ensure the existence and stability of a unique equilibrium point of unforced first-order fuzzy relational dynamical systems by using two different approaches which are both based on the fuzzy relational matrix of the model.In the first approach, the equilibrium point of the system is one of the centers of the related membership fu...
متن کاملA NEW APPROACH TO STABILITY ANALYSIS OF FUZZY RELATIONAL MODEL OF DYNAMIC SYSTEMS
This paper investigates the stability analysis of fuzzy relational dynamic systems. A new approach is introduced and a set of sufficient conditions is derived which sustains the unique globally asymptotically stable equilibrium point in a first-order fuzzy relational dynamic system with sumproduct fuzzy composition. This approach is also investigated for other types of fuzzy relational composit...
متن کاملReliability analysis of repairable systems using system dynamics modeling and simulation
Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...
