step is establish a suitable mathematical model to describe the behavior of the controlled plant (Takagi & Sugeno, 1985;Ying et al., 1990).However, in practical situations, such a requirement is not feasible because in practical control systems the plants are always nonlinear systems, which makes this task analytically unfeasible for complex systems (Cetin & Demir, 2008;Dong et al., 2009;Park et al., 2007;Pelladra et al., 2009).This fact has motivated the use of fuzzy logic in the development of fuzzy model based control systems.In this context, The Fuzzy Systems have been widely used due to flexibility of its structure to incorporate linguistic information (knowledge expert) with numerical information (sensors and actuators measurements), as well as its functional efficiency as universal approximator capable of treat adequately uncertainties, parametric variations and nonlinearity of the plant to be controlled (Castro-Sitiriche et al.
