abstract

A new consensus based active vibration controller for distributed parameter system is developed and presented in this paper. The controller is made of multiple parallel first-order integrator filters that have consensus goal of suppressing resonant modes of an oscillating structure. Each actuator on the structure is designed to work as a node of the network. Together through the consensus communication topology of the controller the structural vibrations are suppressed. To validate the results a numerical study has been performed on a flexible cantilever beam structure. The results presented in this paper will show that the new controller works effectively, and is robust to failures and inconsistencies in the control system.
