In this paper we discuss the vibration control of a flexible structure which possesses transverse-torsional coupled vibrations using two active dynamic vibration absorbers. The H-infinity control theory is adopted to obtain an output-feedback robust controller by which structural vibrations in two lower vibration modes are reduced without spillover. The statements of the control object are organized into the generalized plant, robust stabilization and sensitivity reduction. A method of systhesis of the controller is presented in which balancing of control inputs is taken into consideration. In the numerical analysis and the control experiments, it is confirmed that the controller achieves a considerably high performance with robust stability.
