This Paper describes a general control system design method for vibration of a multi-degree-of-freedom system. A H controller designed on the reduced order model makes the closed loop system not only cause no spillover phenomena, but also control the vibration on the actual model. The solution to H output feedback control problems is used to design the H controller. With the result of calculating the example of the four-degree-of-freedom model, the efficiency of the control system is verified. Also, the frequency-shaped LQG control desigh is made in comparison with the H optimal control. It has been clear that both control methods have robustness to the spillover caused by the reduced-order model in the case of the same weighting functions. The most important result is that the H optimal control has strongly robust stability to parameter variations, while the frequency-shaped LQG control does not.
