Research on position control system of mechanical structure of high power laser device

当前调姿控制系统存在误差大、抗干扰性能差和反应耗时长的问题,设计了一种高功率激光装置机械结构件调姿控制系统。系统中央控制模块负责各单元分工、交互界面及数据处理,根据需求和现场环境不同,利用不同底层通讯技术实现系统通讯,系统软件分为自动调姿程序和逻辑控制程序,自动调姿程序通过激光跟踪器得到激光装置机械构件测量信息并构建测量场,得到构件初始姿态,逻辑控制程序利用各种参量判断系统工作状态,基于中央操作指令、逻辑需求及实时监控结果,给出相应动作指令,实验结果表明,该系统控制误差率在7%以下,抗干扰性能和异常反应耗时均优于当前系统。

There are some problems in the current attitude control system, such as large error, poor anti-jamming performance and long reaction time. The central control module of the system is responsible for the division of labor, interactive interface and data processing of each unit. According to the different needs and field environment, the sys tem communication is realized by using different underlying communication technology. The system software is divided into automatic attitude adjustment program and logic control program. The automatic attitude adjustment program ob tains the measurement of the mechanical components of the laser device through the laser tracker. Based on the central operation instructions, logical requirements and real-time monitoring results, the corresponding action instructions are given. The experimental results show that the control error rate of the system is less than 7%, and the anti-interfer ence performance and abnormal reaction are achieved. The time consumption is better than current system.
