捕获轨迹试验装置（captive trajectory simulation system，CTS）是在风洞中进行外挂物分离试验、对分离轨迹进行模拟的多自由度机构。首先对风洞中CTS的连续动态轨迹试验方式的基本过程和实现进行了说明。主要对多自由度机构在动态生成轨迹中的连续同步控制和天平信号的实时处理问题进行了详细介绍。采用了非线性实时迭代优化算法设计实现CTS多自由度机构的缓冲同步控制算法，解决动态轨迹的连续同步控制问题；运用零相位偏移的数字滤波器设计小滞后的实时滤波算法，实时提取天平信号的有效信号。最后将CTS 连续动态轨迹试验方式的风洞试验数据与传统的位置控制方式的试验数据进行了对比。结果表明，在相同条件下，连续动态轨迹试验方式减少风洞CTS的试验时间约60％，所产生的分离轨迹数据与位置控制方式一致。

The captive traj ectory simulation system (CTS)is a multi-degree of freedom mechanism used in wind tunnel as a tool to simulate the separation trajectory of the store after it separates from the mother plane. The general concept of the continuous coordinated control of CTS along dynamically generated traj ectory is illus-trated at first.The two main technical problems in the dynamic continuous control of the CTS jig,which are the continuous dynamic coordinated control of the jig and the signal processing of the balance signals,are discussed in detail.By applying a real-time iterative nonlinear optimiztion method,an optimized coordinated control algo-rithm is designed.A real-time filtering algorithm with short-latency is also designed by deploying the zero phase shift digital filter which can extract the effective signal from the banlance signals.The wind tunnel test results show that,given the same initial test conditions,the resulting simulation trajectories generated by the continu-ous control method are overall identical to the trajectories generated by the move and stop control method. While the former control method has greatly improved the test efficiency of the CTS traj ectory simulation in wind tunnel.About 60 percent of wind tunnel running time and gas consumption can be reduced.
