System identification and robustness verification techniques are implemented for vibration control of flexible structures. This control methodology allows engineers to develop models which account for parametric uncertainties in a system. The test bed is a 10-bay aluminum truss-like structure. A reaction mass actuator (RMA) is used as the force actuator device for controlling the structure. A local velocity feedback controller is utilized to suppress structural vibration. Added masses to structural nodes represent parametric uncertainties. Interval control system analysis was applied to show the limits of performance of the uncertain experimental system
