Comparison of Control Strategies for Active Vibration Control of Flexible Structures

In recent years several strategies for active vibration control of weakly damped flexible structures have been presented. Depending on the type and location fo actuator and sensor different control strategies lead to different performance and robustness behaviour oh the closed loop. The aim of the paper is to present convenient actuator-sensor-controller combinations and to compare their closed loop performance. A test rig representing a gantry milling machine allows ti validate practical applicability.
