technical field [0001] The invention relates to an ultrasonic motor drive controller, in particular to an ultrasonic motor drive controller based on an embedded system level chip. Background technique [0002] Ultrasonic Motor (USM) is a new type of motor made of functional materials. It uses the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration to amplify the microscopic deformation of elastic materials (piezoelectric ceramics, PZT) through resonance and Frictional coupling translates into macroscopic motion of the rotor or slider. Due to its unique operating mechanism, USM has advantages that traditional electromagnetic motors do not have: simple and compact structure, low speed and high torque, no need for deceleration mechanism, flexible and diverse forms, etc. Nanotechnology, military industry, robotics, biology, medical machinery, aerospace, office automation and other fields have shown great application potential and advantages.

Problems solved by technology

[0003] At present, the matching circuit of the ultrasonic motor driver is usually implemented with series inductors, so that the voltage applied to the ultrasonic motor changes greatly during frequency modulation. If the frequency modulation is to ensure that the motor voltage remains unchanged, the input voltage must be adjusted after adjusting the frequency. This complicates the control of the motor
