A distributed active vibration control system based on the wireless sensor network for automotive applications

Abstract

This paper presents a new approach of an adaptive vibration control system for automotive applications. We assume that a porting of a centralised system in a distributed system can improve its effectiveness. We present a wireless sensor network (WSN) for vibrations damping. These autonomous sensors are able to measure the vibrations, damp the vibrations and to harvest energy from vibrations by using a single piezoelectric element. We present the simulations and the measurements results. The new approach of distributed active vibration control system based on the wireless sensor network is presented. The designed distributed wireless network node reduces the vibrations of the plate with the efficiency up to 9.4 dB.
