This paper introduces a soft-computing oriented approach to Takagi-Sugeno fuzzy modelling using the evolutionary principles. Genetic algorithms are applied to optimize fuzzy input variables space through genetic fuzzy clustering procedure and to identify the fuzzy model. Some advanced procedures e.g. individuals lifetime limitation and redundant genes application are used. The presented algorithm allows also the determination of the relevant inputs variables of fuzzy model from theirs potential candidates. To clarify the advantages of the proposed approaches the numerical example of modelling of fuzzy non-linear system is also introduced.
