N2 - In order to analyze and design an ultrasonic motor (USM) control system, an accurate and reliable mathematical model should be established. Due to the nonlinear characteristics of the motor, which are resulted from special structure and complicated working principle, traditional modeling methods are no longer applicable. Nonlinear Hammerstein model structure is proved to be a better choice for describing nonlinearities in operation after years of study and practice. The Hammerstein model of the equivalent circuit model can be established to simulate the process of modeling the actual motor since both of the two models are in a one-to-one correspondence with the motor. In this paper, following the establishment of the equivalent circuit model, a model based on this idea is established with two-phase driving voltage as its inputs. The complete modeling process is given and the method is applied to an actual ultrasonic motor, which verifies the effectiveness of the proposed method.
