To decrease a vibration with the robustness is necessary to control a flexible structure. In this paper, we discuss a robust vibration control for a time varying two-link-beam model regarded as a simple model of a flexible structure. We provide a design method of a robust vibration controller for the system. The controller is designed with, so-called, the design method of a constant-matrix-scaled quadratic stabilization. By this method, the H-infinity norm of the target transfer function is decreased, the gain of the designed controller becomes high and the controller becomes to have a derivative effect. Therefore, we can say that the resultant control system becomes a robust vibration control system for time varying systems. Finally, with some simulations, we show that the design method has effectiveness.
