Abstract

A typical vibration rest for a specimen is to subject it to a specific spectrum of random vibration. This paper proposes multi-resolution processing using a "frequencv domain self-tuning" algorithm for application to random vibration control. MATLAB programs simulate two-octave-band and three-octave-band processing for random vibration control. A PC-based, digital signal processing (DSP) board was used to implement wo-octave processing. The simulation and practical results are presented.
