A study on the application of digital twin technology in speed monitoring of ultrasonic motor

With its unique advantages, ultrasonic motors are favored in aerospace, robotics, automation equipment, precision instrumentation, etc. Aiming at the phenomenon of unstable motor speed caused by the influence of ultrasonic motor's material properties, wear, and environmental factors, this paper proposes the use of digital twin technology to carry out dynamic real-time monitoring of ultrasonic motor. Based on the analysis of the operation mechanism and control mode of the ultrasonic motor, and the digital twin technology, a digital twin model of the ultrasonic motor is constructed, and the realization process of the digital twin ultrasonic motor speed monitoring is explained.
