摘要

    摘要
  • 摘要: 为了对控制系统稳定性能和扰动隔离能力进行分析，对二级稳定系统进行了建模和控制器设计，仿真结果显示，系统速率稳定回路带宽提升至200 Hz，1 Hz位置隔离度提升至-90.1 dB。在实际系统中，采用位置敏感探测器（PSD）测量瞄准线的运动，隔离度测试实验结果显示1 Hz位置隔离度提升至-73.1 dB，提升约20 dB，测试结果证明:二级稳定技术能够显著提高系统的稳定精度。
    Abstract: In order to analysis the stabilized and isolated ability of control system, the model of two-level stabilization system was established and the controller was designed.The result of simulation showed that the bandwidth of rate stabilized loop was improved to 200 Hz, the isolation at 1 Hz reached -90.1 dB. The error of line of sight(LOS) was measured by position-sensitive detector (PSD),the result of isolation testing experiment showed that the position isolation at 1 Hz reached -73.1 dB,increased by 20 dB approximately,which implied that the stabilized precision could be improved significantly by two-level stabilization system.
