Stabilzing the 1-Periodic Response of a Beam With One-Sided Spring; Experiment Versus Simulation

摘要

Stabilizing the 1-periodic response of a haramonically excited multi-DOF beam with one-sided spring is demonstrated by controlling the system state from the stable large amplitude 2-periodic response to the coexisting unstable small amplitude 1-periodicresponse. At the 1-periodic response is a solution of the uncontrolled system. The control force will be based on two control techniques, namely partial feedback liinearization and linear error feedback.For both techniques, results from real experiments are compared to results from numerical simulations.
