The recurrent dynamic fuzzy logic system and nonlinear system identification

A recurrent dynamic fuzzy logic system, RDFLS, is introduced and its universal approximation property proved. A RDFLS based stable adaptive identification algorithm is further developed and its stability properties investigated theoretically. The application of this identification algorithm to nonlinear systems is demonstrated via simulation examples, and satisfactory results are observed, which indicates the usefulness of the RDFLS in the identification of nonlinear systems.
