Semi-Active Vibration Isolation Control Using Feedforward Information of Disturbance
View through CrossRef
Abstract
Since the suppression of actuator power for active structural vibration control is an important problem, semi-active control methods receive much attention. In this paper, a new semi-active control method for the vibration isolation is presented. By taking the dynamics of disturbance into consideration, the optimal control method is applied to the augmented system that includes both the control object and the disturbance. By utilizing the obtained control law with a feedfoward link of disturbance, it is used for the semi-active control law based on the semi-active constraint of variable damper.
The control method was applied to the 4-DOF structural vibration isolation. The numerical analysis showed that the method has high control performance in a wide frequency range, and it is effective for the vibration isolation of building structures.
