Linear stability analysis of piezoelectric controlled beams subjected to nonconservative loads

Discrete model of piezoelectric controlled beams, subjected to follower forces, are studied in this paper. The failure of a similar controller in improving stability properties of the beam is also discussed, this being in contrast with the common practice in the use of piezoelectric devices for which similarity is requested in order to maximize the energy exchange between structure and controller. Moreover, three novel linear gyroscopic controllers are proposed and, by making use of eigenvalues sensitivity analysis, their effectiveness is discussed.
