This paper studies a control of vortex-induced vibrations of a circular cylinder supported by a cantilever beam. A servo motor is installed as an actuator to suppress the vibration of the system, and the beam is clamped at the axis of the motor. The beam-cylinder system is hanged in front of an air tunnel and allowed to tilt statically. When the wake frequency coincides with the natural frequency of the structure in the uniform flow, resonant vibration may occur and this is known as the rock-in phenomena. In this research, feedback control by the linear quadratic regulator and a disturbance cancellation control by the minimum order observer are applied to the system for vibration reduction. Performance of each control law is investigated by the numerical simulation.
