Abstract :
This paper proposes an interval type-2 recurrent fuzzy neural network (IT2RFNN) for dynamic system identification. The antecedent parts in each recurrent fuzzy rule in the IT2RFNN are interval type-2 fuzzy sets, and the consequent part is of the Takagi-Sugeno-Kang (TSK) type with interval weights. The recurrent structure in the T2RFNN enables it to handle dynamic system identification problems with a priori knowledge of system input and output delay numbers. A T2RFNN is constructed using concurrent structure and parameter learning. Simulations on dynamic system identification with clean and noisy outputs verify the performance of T2RFNN.
