Abstract

The results of simulations to demonstrate decentralized vibration control with a netowkred embedded system are presented in this work. Conventional vibration control designs rest on centrality, and the central processor deals with information of the entire system. When large-scale systems are considered, decentralized vibration control system provides an alternative design. The simulated system in this work is a simply supported beam that is collocated with 50 localized processor nodes which can communicate with each other. Each node will calculate and supply the control force to control the beam vibration according to the shared sensor information among the nodes and an optimal direct velocity feedback algorithm. The simulation results demonstrate that decentralized vibration control can achieve a global control objective, making it suitable for large-scale systems. The effects of network communication delay and feedback architecture on control performance are demonstrated.
