Hysteresis is an important nonlinear effect exhibited by piezoelectric actuators (PEAs) and its modeling has been drawing considerable attention. This paper presents the development of a novel discrete model based on the concept of autoregressive moving average for the PEA hysteresis, and its parameter identification method as well. Experiments were carried out to verify the effectiveness of the developed model. The result obtained shows that the developed model can well represent the PEA hysteresis, with improved performance over an existing discrete hysteresis model.
