    摘要:

    终端光学组件及反射镜架是激光约束核聚变装置中的重要组成部分,具有运动轴数量多且分散的特点,为实现该设备的运动控制,采用分布式控制的思想,建立了以倍福嵌入式PC和总线端子为底层控制器,以EtherCAT网络为通讯的控制系统结构.控制软件在VC++和TwinCAT的环境中开发,对于机械系统要求的特殊功能均编制成PLC功能模块,并在下位机中运行,包括电机上下电锁紧功能、自动上下电功能、某个运动轴的手动跟随功能、单向定位功能.其中单向定位控制功能的应用将重复定位精度控制在3μrad以内.这种分布式控制系统具有结构简单、成本低廉、通讯速度快等特点,在实际工程应用中稳定、可靠.

    Abstract:

    Terminal optical module and reflector mount are the important components of laser-driven inertial confinement fusion (ICF) device, having the characteristic of owning much and scattered motion axes. The control system that can achieve the motion control of this device is built upon the thought of distributing control. The system contains Beckhoff embedded PC and bus terminals as underlying controller and EtherCAT as the communication network. Software of the control system is developed under the VC++ and TwinCAT environment. The special functions required by mechanical systems are all be programmed to the PLC function block and work in the clients, such as the function of motor lock when power up and down, the motor’s automatic power-up, certain moving axis’ manual follow, one-way positioning,and so on. Among these functions, one-way poisoning can make sure the repeat location accuracy within 3μrad. The control system has the characteristics of simple construction, low cost and fast communications speed. It can keep stable and reliable in the practical engineering applications.
