文摘

This study deals with the problem of reducing the amplitude vibration of flexible structures. Piezoelectric ceramics have been chosen as actuators. After modelling, we derive the corresponding equations governing the dynamic behaviour of structures under control. An analytical approach has been developed to obtain accurate control parameters and tested numerically. A variety of voltage source conditions on control design have been explored. These have been tested numerically.
