Abstract

This work focuses on developing an optimization strategy for determining the parameters of a compliant actuator to achieve effective control of vibration transmissibility. The investigation on passive and active control characteristics of the compliant actuator are conducted in relation to the compliant stiffness and damping parameters, which reveal a strong influence of the parameters to the overall passive-active vibration suppression performance. An optimization strategy for the compliant actuator system is proposed by minimizing the H2 norm of the transfer function associated with the force transmissibility of the system, while the active control performance is investigated by using the derivative-type controller. The effectiveness of the proposed optimization strategy is demonstrated by comparison of various compliant actuator systems and the conventional rigid actuator system. It is shown that the overall passiveactive control vibration performance can be improved satisfactorily.
