Research on Random Vibration Control Algorithm Based-on EV Model

摘要：

　　In order to improve the accuracy of random vibration power spectrum playback experiment,The traditional FRF H1 estimation has improved.The methods of FRF estimation have been proposed based on EV model for the H1 under-estimation problems.The FRF H1 estimator is updated based on the power spectral density (PSD) of the noises and inputs of the system,and describes the principle and process of random vibration control algorithm based on EV model,and finally the acceleration power spectrum playback experiment verify the validity of the algorithm.

关键词： random vibration EV model FRF estimation PSD (power spectral density)
