In order to identify the inherent hysteresis characteristic of the piezoelectric actuator, a modeling scheme based on the interval type-2 Takagi-Sugeno(T-S) fuzzy system is proposed in this paper. First, the vertical distance formula is used to replace the traditional error calculation formula, so that the clustering algorithm is directly related to the identified regression plane results, and a modified interval type-2 fuzzy C-regression model(FCRM) clustering algorithm is proposed to divide the fuzzy space and improve the accuracy of interval division. Second, in view of the problem that the hyperspherical Gaussian membership function does not match the structure of the hyperplane clustering algorithm; the hyperplane membership function matching with the hyperplane is introduced to complete the identification of the fuzzy antecedent parameters, and the least square method is used to identify the fuzzy consequent parameters. Finally, the hysteresis characteristics of the piezoelectric actuator are modeled by using the above-mentioned scheme. The effectiveness of the proposed modeling method is verified by experiments.
