Abstract
Linear ultrasonic motor has a wide range of applications in the aerospace field, which requires not only high accuracy of the control, but also the need for a stable running speed. For broadening its application, it is necessary to keep the linear ultrasonic motor having a stable speed. This paper first proposes AR module method for linear ultrasonic motor. The speed of the linear ultrasonic motor is measured by the driving and controlling system. By minimizing the targeted speed value and the actual speed value, we can keep the linear ultrasonic motor stable. This text also compares this method with the traditional PID method. The average deviation of AR is 24%.
