Active Vibration Control of a Suspension Bridge using Eigenvalues Move Method

This paper describes a numerical search-based algorithm (called Eigenvalues Move Method) to design feedback gains of a vibration control device for a flexible structure. Eigenvalues Move Method (EMM) is a simple and efficient method which can derive output feedback gains assigning the poles of the closed loop system by a specification of required damping ratios. The effectiveness of the designed controller was proved by performing a series of simulation and experiments on an actual tower (2P tower of KURUSHIMA BRIDGE).
