| 对随机角振动控制系统进行了研究，目的是为了实现随机控制技术在角振动上的应用。利用设置的参考谱与反馈的响应信号功率谱来修正驱动谱，根据驱动谱产生驱动信号，利用驱动信号与反馈的响应信号实时精准地控制角振动台进行角振动，最终实现响应谱稳定在参考谱容差带范围以内。通过构建出控制系统，分析控制算法，解决了角振动台进行随机角振动的实现问题。实验验证了控制算法的可行性和控制系统的可靠性，完成了角振动台转动的角速度和角加速度的功率谱复现。 |

| The random angular vibration control system is studied in order to realize the application of random control technology to angular vibration. By setting the reference spectrum and feedback response signal power spectrum to modify the driving spectrum, we can generate driving signals according to the driving spectrum, control the angular vibration table of angular vibration in real-time accurately by using the driving signals and response signal feedback, and finally realize the stable response spectrum in the reference spectrum with tolerance range. By constructing the control system and analyzing the control algorithm, we solve the problem of realizing the random angular vibration of the angular vibrator. The feasibility of the control algorithm and the reliability of the control system are verified by the experiment, and the power spectrum of angular and angular acceleration of the angular vibrator is completed. |
