Evolution of Digital Vibration System

Digital vibration control systems are discussed in this paper, from their inception to the present. Current models include sine, transient or shock, and random test features. The current state-of-the-art in commercial vibration control systems is presented, with a summary of their performance and features. Future systems are discussed, showing the trend in control development that will permit practical implementation of multichannel and multiaxis control. The use of digital vibration for design is discussed, whereby testing and evaluation can together modify original designs.
