OPTIMAL PARAMETERS FOR NEGATIVE STIFFNESS CONTROL BASED ON SKYHOOK CONTROL ANALOGY
Various vibration control methods, including the skyhook control and the negative stiffness control, have been proposed to achieve dynamic response reduction in terms of the absolute response. It is often observed that negative stiffness appears in the behavior of control devices following the skyhook control. In this study, negative stiffness appearing in the skyhook control method is theoretically evaluated with the use of equivalent control parameters in the negative stiffness control. Based on the result, relevance of the negative stiffness control to the skyhook control and the significance of negative stiffness are discussed, and the optimal design of the negative stiffness control is proposed.
