N2 - Several non-linear systems show complex behaviors. For example, some of those plants present a high degree of oscillations througout the time. Adaptive algorithms used to approximate such difficult behaviors can show important deficiencies. The differential neural network is not an exception. Indeed, when just one neural network is applied to get an adequate approximation, the identification error could be not so close to zero. One possible suggestion to solve this problem is to deine a set of neuronal networks that works together. The members of such set will work each one on well deined trajectories subspaces of the uncertain system. In this paper, it is disscused how to combine the identiication properties offered by the continuous neural network and the characteristic decision capabilites arised by fuzzy methods. The selection of which neural network is activated depends on decision achieved by a takagi-sugeno fuzzy system. The Chen circuit will be used to demostrate the superior performance achieved by the suggested class of mixed neural network and fuzzy system, usually so-called neuro-fuzzy system.
