一种新的大行程垂直纳米运动工作台设计与控制研究
Design and Control of a New Long-Stroke Vertical Nano-Motion Stage
摘要
Abstract
The design and stable control of the stage are key factors in large stroke high-precision vertical motion.Therefore,a novel motion stage with a balancing mechanism is proposed to achieve large stroke nano stable motion in the vertical direction.The characteristics of the stage are that the N331 piezoelectric linear motor is independently driven,suspended through the air static guide rail,and the Z-axis balance system is designed to reduce the motor driving load.A stepping mode is used to realize the large travel actuation,and an analog mode is adopted to implement micro-displacement actuation.This strategy can be used to achieve fast and precise driving of 100 mm.In addition,the Z-stage can achieve compound control of the nanostepping and analog modes.The positioning fluctuation can be limited to±9 nm within the full range of 100 mm.According to the verification experiments,the stage can be suitable for driving and control tasks in coordinate measuring machines(CMMs),microlithography,and micromachining applications.关键词
