Research on the Random Angular Vibration Control System

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.
