A Fractional-Order Normalized Bouc-Wen Model for Piezoelectric Hysteresis Nonlinearity

16 Aug 2020 Kang Shengzheng Wu Hongtao Li Yao Yang Xiaolong Yao Jiafeng

This paper presents a new fractional-order normalized Bouc-Wen (BW) (FONBW) model to describe the asymmetric and rate-dependent hysteresis nonlinearity of piezoelectric actuators (PEAs). In view of the fact that the classical BW (CBW) model is only efficient for the symmetric and rate-independent hysteresis description, the FONBW model is devoted to characterizing the asymmetric and rate-dependent behaviors of the hysteresis in PEAs by adopting a generalized input function and two fractional operators, respectively...
