音圈电机驱动系统

摘要

近年来，随着我国科技的发展与进步，直线驱动技术以及其控制方法也在不断的改进。音圈电机是一种具有特殊结构的新型直接驱动电机，它具有体积小、结构简单、快速响应、高加速度等特性。由于对快速速、高精度定位系统性能要求的提高和音圈电机技术的快速发展，音圈电机不但被广泛应用在激光唱片、磁盘定位等精确定位系统中，在很多其他形式的高速度、高频激励中起到了广泛的应用。如，机械工具的多坐标定位系统、光学系统中透镜的快速定位、减小振动对隔振技术平台的影响、以及医学领域精密电子管的控制等。

本文从音圈电机的工作原理以及其PID控制方法角度对音圈电机的驱动系统展开研究。

Abstract

In recent years,as the development and progress of our country’s science and technology, linear drive technology and its control method is also in constant improvement.V oice coil motor is a new type direct drive motor with special structure.It has small volume,simple structure,fast response,high acceleration and other features.Due to the rapid speed,the improvement of high precision positioning system performance requirements and the rapid development of voice coil motor technology.V oice coil motor is widely used not only in the CD,disk positioning accurate positioning system,but also in many other form of high speed and high frequency excitation.Such as machine tool coordinate positioning system,the lens in the optical system of fast positioning,and reduce the influence of vibration on

vibration isolation technology platform and precision control of tube and medical fields.

This article analyze the drive system of voice coil motor from the principle of voice coil motor ,and the PID control method .

Key words:voice coil motor;direct drive;PID control
