| Description: |
The perspective of using piezoelectric motors in micro and nano-scale systems used in the production of integrated circuits, genetic engineering for manipulations within individual living cells, etc., makes the problem of their constant improvement a high-priority task.Recently, considerable attention is also paid to the usage of piezoelectric motors as microcontroller drives for the manufacture of micro-units, cutting tools based on individual diamond crystals, cutting, drilling and grinding of ruby stones for mechanical or electromechanical devices.In such case, there is a need for continuous improvement of piezoelectric motor control systems to ensure stability in all possible operating modes.This paper considers the possibility of improving the accuracy of the piezoelectric motor control, specifically, current and speed, taking into account the specificity of the frequency response of a piezoelectric motor with a rectangular resonator.The control systems (by current and speed) are proposed by a piezoelectric motor with a rectangular resonator taking into account the specificity of the frequency characteristic of the piezoelectric element and the motor.The system for stabilizing current and speed is developed and tested on serial piezoelectric motors.The accuracy of control on serial motors (LPM-2M, LPM-5, PM-1124) is confirmed at a current of 1 . 2% at a speed of 2-5% with a significant expansion of the control range towards the micro- and nano-velocity side.The offered control systems of piezoelectric motors with a rectangular resonator, which increase the accuracy of micromanipulation systems and precision instruments to dozens of nanometers and extend the temperature-operation range from -50°С to + 80°С due to compensation of the temperature shift of the engine’s resonant frequency, and also provide stability of constant speed at working values of torque and force, and stable operation in pulsed control mode. ; В работе рассмотрена возможность повышения точности управления пьезоэлектрическим двигателем, а ... |
