摘　　要：针对超声波电机转速控制应用,以实验数据为基础,采用模糊逻辑方法建立了超声波电机系统的二输入单输出稳态模糊模型。数据验证表明,该模型较好地模拟了电机驱动电压幅值、频率及转速三者之间的非线性关系。文中详细描述了模糊建模过程,为超声波电机系统的非线性控制建模提供了另一条有效途径。Aiming at speed control of ultrasonic motor, the two-input and one-output stable model of ultrasonic motor system was worked out using fuzzy reasoning modeling method. Based on the experimental data, comparison between experimental data and calculated data of the model prove that, the model can well simulate the nonlinear relationship among the amplitude of driving voltage, frequency and rotating speed. The process of fuzzy modeling was described in detail, which gave another effective method for the modeling of ultrasonic motor.
