The design of a novel, single-axis ultrasonic actuating stage has been proposed. It consists of a movable plate, an edge-driving ultrasonic actuator as an actuating device, and a magnetic Magi encoder as a position sensor. The stage is impelled using a friction-contact mechanism by the ultrasonic actuator with long distance movement. Very high actuating and braking abilities are obtained. The stable and precise positioning control of the stage was achieved by using a neural-fuzzy controller. This simple and inexpensive structure of the single-axis stage demonstrates that the mechanical design of ultrasonic actuating concept could be done flexibly according to the requirements for various applications.
一种新型单轴超声驱动平台的设计方案已被提出。它由一个可移动板、一个作为驱动装置的边缘驱动超声致动器以及一个作为位置传感器的磁致编码器组成。该平台通过超声致动器利用摩擦接触机制进行驱动,可实现长距离移动。获得了非常高的驱动和制动能力。通过使用神经模糊控制器实现了该平台的稳定精确的定位控制。这种单轴平台简单且成本低廉的结构表明,超声驱动概念的机械设计可以根据各种应用的需求灵活进行。
