Hierarchical Decentralized Robust Control Method of Uncertainty Structure Vibration

  • Received Date: 02 Jul 2008
  • Publish Date: 20 Apr 2009
  • Based on the linear matrix inequality,a hierarchical decentralized state-feedback controller was given to resolve the vibration control of an uncertainty building structure.Active control experiments were constructed by a Matlab/xPC real-time control system,and half physical real-time data acquisition and control of a cantilever beam were realized by using piezoelectric materials,showing a favorable performance even if when the mass of a structure changes.The time domain analysis indicates that the vibration attenuates quickly with the increase of a distance away from the vibration source.The experimental result shows that the controller can work very well,and this method has strong robustness.
