Control of pullin dynamics in a nonlinear thermoelastic electrically actuated microbeam

  title={Control of pullin dynamics in a nonlinear thermoelastic electrically actuated microbeam},
  author={Stefano Lenci and Giuseppe Rega},
This work deals with the problem of controlling the nonlinear dynamics, in general, and the dynamic pull-in, in particular, of an electrically actuated microbeam. A single-well softening model recently proposed by Gottlieb and Champneys [1] is considered, and a control method previously proposed by the authors is applied. Homoclinic bifurcation, which triggers the safe basin erosion eventually leading to pull-in, is considered as the undesired event, and it is shown how appropriate controlling… CONTINUE READING
