The effect of high-frequency AC electromagnetic actuation (EMA) on the dynamic behavior of a harmonically excited cantilever beam is analyzed in this paper. Analytical treatment based on perturbation analysis is performed on a simplified one degree of freedom equation modelling the first bending mode of the cantilever beam. The results show that under a certain specific condition relating the intensity of the fast AC to the displacement, the nonlinear characteristic of the system can be controled.
