Abstract

This paper concerns the use of fuzzy structures to model non linear dynamic systems. An interval type-2 Takagi Sugeno Kang fuzzy logic systems (IT2 TSK FLSs) is proposed. The proposed approach is a combination of IT2 fuzzy system and TSK fuzzy models and it presents an extension of the type-1 Takagi Sugeno Kang fuzzy logic system (T1 TSK FLSs). The interval type-2 fuzzy sets provide additional degrees of freedom and offer the capability to directly handle uncertainties. Different steps of this approach are described. The performance of the IT2 TSK FLSs is compared to the traditional T1 TSK FLSs. Simulation results performed on three tank system illustrate the efficiency of the suggested method.
