Design and Analysis of a Wideband Random Vibration Controller

An implementation method is presented for a random vibration controller,which can produce real-time vibration exciting signals with high accuracy.With this method,the signal-to-noise ratio of wideband random signal can reach 70dB,and it can be used in the driving control signals of random shaking table with high precision.Simulation is carried out successfully on the tested products.The computer simulation and test results demonstrate the validity of the proposed method.
