为满足2m 量级超声速风洞外挂物捕获轨迹试验的需要，研制了2m×2m 超声速风洞 CTS 试验装置，开发了相应的信号测量与运动控制系统。为确保 CTS 速度闭环控制试验方式的实现，选择了具有集中控制的多层分布式结构，以满足该试验方式对测控系统的实时数据处理及信息交互能力的较高要求。系统由信号测量与轨迹运动方程求解子系统、六自由度装置运动控制子系统和安全监控子系统等构成。采用 NI 公司的图形化编程语言LabVIEW 开发了监控管理软件、数据采集和轨迹生成软件、安全监控软件。采用力士乐公司的 IndraWorks 完成了运动控制执行软件的开发。子系统间分别运用了 TCP／IP、PSP、Profibus DP 等通讯协议实现信息交互。解决了系统抗冲击及速度控制等关键技术难题。研制完成后采用 T3-40激光跟踪仪对六自由度装置的静态精度进行了测量，其中线位移 X 、Y 、Z 的定位精度达到0．021、0．046和0．094mm，角位移α、β、γ的定位精度达到0．05°、0．047°和0．022°，定位精度全部优于设计指标（±0．1mm、±0．1mm、±0．1mm、0．05°、0．05°和0．05°）。地面调试和风洞试验验证表明：CTS 测控系统运行稳定，操作方便，维护简便，试验结果合理、可靠。

In order to meet the requirement of Captive Trajectory Simulation tests in 2m-scale supersonic wind tunnel,the CTS facility and the corresponding measurement and control system are developed in the 2m×2m supersonic wind tunnel.In order to realize the closed-loop velocity control mode,a multi-layer distributed structure with a centralized control test technique is selected for the construction of the measurement and control system which must meet the high demands of real-time processing and information interaction tasks.The system consists of three subsystems,namely,the signal measurement and motion equation solver subsystem,the 6-DOF motion control subsystem ,and the safety supervising subsystem.The softwares of monitoring and management,data acquisition and trajectory generation,and security monitoring are devel-oped by LabVIEW.The motion control execution software is developed by IndraWorks.The information interaction among subsystems is implemented through TCP/IP,PSP and Profibus DP.The key technical problems such as shock resistance and velocity control are solved.Static accuracy of the 6-DOF rig is measured by T3-40 laser tracker which shows that the positioning accuracy of linear displacement X ,Y and Z achieves 0.021mm,0.046mm and 0.094mm respec-tively,the positioning accuracy of angular displacement α,β and γ achieves 0.05°,0.047° and 0.022°,respectively.The accuracy is better than that of design index(±0.1mm,±0.1mm, ±0.1mm,0.05°,0.05°,0.05°).The debugging and wind tunnel tests show that the system is sta-ble,reliable,and easy to use and maintain;the test results are reasonable,and the data obtained are reliable.
