“…Each of these hysteresis models has some disadvantages. For example, the polynomial hysteresis model (Wei and Sun, 2002;Lining et al, 2004) may cause errors if the amplitude of the desired input is not of the same order as that of the original signal. On the other hand, elliptical models (Gu and Zhu, 2010) only describe symmetrical hysteresis through mapping the hysteresis loop into a family of ellipses.…”

This work presents a dynamic model of a smart fin that is activated by a piezoelectric bimorph actuator, which is made by bonding two MFCs. The actuator is completely enclosed within the fin. Earlier research has indicated that the use of a linear model for the fin dynamics does not fully describe the fin. This work presents a more realistic approach to this problem by incorporating additional components into the model. Therefore, a proportional damping matrix is introduced. It is also observed that experimental results exhibit hysteresis and backlash. A Bouc-Wen hysteresis model, combined with four backlash operators, is proposed. These backlash operators are used to model the observed saturation and the non-symmetry of the response. HFSGA is used to identify the optimal set of parameters for the damping matrix constants, the Bouc-Wen model, and the backlash operators. One input case is considered for training the genetic algorithm. The results show that proposed model can predict the hysteresis of the smart finactuator system under various operational conditions.
