This is positive significance to the determination of ultrasonic motor. It is control strategies and development of ultrasonic power supplies as well as the promotion and use of ultrasonic motors. In order to meet the control requirements of piezoelectric plate sensor, rapidity, and simplicity, the domestic and foreign scientific and technological communities and industry have been working on various new types of micro-motors for many years. Ultrasonic motors use the inverse piezoelectric effect of piezo cylinder transducer to transform the microscopic deformation of the material through resonant amplification and friction coupling into macroscopic motion of the rotor or slider. 

As a kind of direct drive motor,piezo plate light sensor has been favored by scientific researchers of all countries since the 1980s. It has become a research hotspot in the field of electromechanical control. This paper first analyzes the operating mechanism of piezo disc element, establishes the formation of the elliptical motion trajectory of the surface particle of the traveling wave ultrasonic motor, and establishes a mathematical model for the traveling wave ultrasonic motor. Then piezo electric disc design the measurement and control system. 

The ultrasonic motor measurement and control system designed in this paper has the following basic functions: (1) Two-way drive signal phase O-1800 continuously adjustable (2) Two-way drive signal can be reversely adjusted to change steering; (3) Frequency output 20kHz ~ 100 Adjustable within kHz; (4) Since the ultrasonic motor to be driven is a capacitive load, impedance matching is required for piezo cylinder transducer. (5) With test and actual operation switching function. (6) It has working status setting, parameter setting, control mode setting, parameter display and waveform tracking function.
