Abstract
This invention provides a control method, apparatus, and readable storage medium for starting an ultrasonic motor. The control method includes: providing driving force to the ultrasonic motor in a first rotation direction at any one or more driving frequencies within a frequency range; and providing driving force to the ultrasonic motor in a second rotation direction at any one or more driving frequencies within the frequency range, wherein the first rotation direction is opposite to the second rotation direction. This invention combines forward and reverse drive switching of the ultrasonic motor with cyclic frequency sweeping to effectively start the ultrasonic motor, and is particularly suitable for situations where the ultrasonic motor has been stalled for a long time.
