Methods are described for calculation of natural frequencies and mode shapes of a cantilever beam with a base excitation and tip mass whose centre of gravity does not coincide with the point of attachment. Exact expressions for natural frequencies and mode shapes are derived. Some typical results ar
The problem of feedback control of vibrations in a micromachined cantilever beam with nonlinear electrostatic actuators is considered. Various forms of nonlinear feedback controls depending on localized spatial averages of the beam velocity and displacement near the beam tip are derived by consideri
