This paper introduces a recursive relation between an existing Takagi-Sugeno-Kang (TSK) fuzzy system of order n and systems of order n-1 and 0. The presented method helps to realize higher order TSK fuzzy systems using first-and zero-order TSK fuzzy system models, which are available in simulation software (e. g., MATLAB and its toolboxes). This method has two major benefits: 1) easier and faster simulation of higher order TSK systems using available software; and 2) possibility of tuning high-order TSK systems by methods like ANFIS, which can only tune first-and zero-order TSK systems. The final section of this paper includes a comparison of simulation speed if the proposed method is used or not and nonlinear function estimation by applying ANFIS on high-order TSK system using the proposed method. Simulation results prove the superiority and usefulness of the proposed method.
