Abstract
The control methods used for shock or free vibration are usually different from those for forced vibration, because shock vibration can be regarded as a type of transient vibration that is different from steady-state forced vibration. In reality, however, both steady-state and transient excitations may occur in transport vehicles, thus there is a need to control both types of vibration. To show the integration of different vibration control strategies, a hybrid control system including a distributed resonant absorber and a distributed shock absorber is proposed. The hybrid system is governed by a control arbitrator that switches a set of sensors and actuators between the two active vibration absorbers according to various external excitation conditions. The effectiveness of the integrated system is shown through simulations and experiments
