| 摘 要： | 双模态超声波电机(USM)在研制的小波差动控制下,提高了双模态USM的低速运行性能,并使双模态USM的驱动分辨率达到了纳米量级.小波差动控制的机理是通过改变双模态USM驱动头的运行轨迹来实现双模态USM的微纳驱动,以及通过控制小波驱动元的触发频率以获取所需的双模态USM步进速度.本文以试验的方式,探讨了双模态USM驱动模型,给出了在小波差动控制下的双模态USM位移驱动特性和特点.

| Abstract: | Bimodal ultrasonic motor(USM) controlled by wavelet differential voltage improves its actuating characteristics at slow actuating velocity and realizes nanometer level actuating resolution.The principle of wavelet differential control is to alter the trajectory of actuating head of bimodal USM to obtain micro-nanometer displacement and to change the triggering frequency of wavelet actuating wave to get different step velocities of bimodal USM.This paper discusses the actuating model of bimodal USM based on ... |
