Active damping technology is one of the effective ways to reduce vibrations. But, the active damping technology is usually applied only for large-size objects such as buildings or trains with the custom-made design because it requires technical knowledge, much man-hour and cost to design. There are few solutions to reduce vibrations after the vibration problems are happened once in product developments. In this study, an all-round active damping system which can be applied for various relatively small-size equipments with add-on style after vibration problems come about was proposed and the features of the system were described. Subsequently, a controller developed for the proposed all-round active damping system was described. This is a distributed controller using real-time network technology and enables following features; high-speed, compact, lightweight, and scalability of I/O number. Finally, as a basic verification, an active damping system with the developed controller was constructed for a metal case as a sample. The gains of resonant peaks from 100 to 300 Hz were damped more than 9.5 dB and it was indicated that the developed controller could be used for the active damping system.
