Control of Structures by Means of High-Frequency Vibration
Abstract In recent years, there has been increasing interest in applications of vibrational control theory [4], [6], [10] to problems of stabilization in mechanical structures. It has been found that high-frequency periodic or quasi-periodic excitation (“vibrational control”) can stabilize an unstable equilibrium position (“vibrational stabilization”). The effect of high-frequency vibration is similar to modification of the “effective potential” of the system and can be achieved either by high-frequency programme control, or by nonlinear feedback control. However, feedback control requires measurement of the system state and costly signal processing, whereas vibrational control can be applied as a pregiven programme. This makes it a powerful tool for stabilization of complicated mechanical systems.
