Active vibration suppression technologies should have high performance and have been studied and applied over the years; however, because of unusability, the practical applications are limited for large objects. Therefore, we proposed the distributed general-purpose active vibration suppression system which can be applied for various relatively small-size equipment with add-on style when vibration problems have occurred, and have developed a network distributed controller which has the following features: high-response rate, compact size, low weight, and scalability of the I/O number. In this paper, the verification of active vibration suppression performance for information equipment or industrial equipment were described. As an actuator for damping, inertial actuator using multilayer piezoelectric devices was developed and the characteristics were investigated. Then, a biaxial active vibration suppression system with the developed actuator for a steel pillar which has two 1st-order inclining modes in two directions was constructed and the both modes were damped more than 15 dB.
