Abstract
A method for the vibration control of an iron cantilever beam using the noncontact force of a permanent magnet is proposed in the paper. The vibration model of the cantilever beam with a tip mass is derived and then updated by experiments. The properties of the force between the magnet and the beam have been determined by theoretic analysis and tests. H∞ control method for the suppression of the beam transverse vibration by the noncontact force of the permanent magnet is put forward. Numerical simulation and actual experiment are implemented by the iron cantilever beam. The results show that the control method is effective and the simulation fits well with the experiment.
