摘要：

This paper describes an experimental study on H(infinity) control for vibration in multi-degree-of-freedom systems. An H(infinity) controller designed by using the reduced-order model makes a closed loop system, not only causing no spillover phenomena, but also controlling the vibration on the four-degree-of-freedom experimental model. The experimental results are very similar to the simulation results, and the efficiency of the H(infinity) control system is confirmed. Also experiments on frequency-shaped cost function LQG (H2) control design are performed in comparison with the H(infinity) optimal control. Because the H(infinity) optimal control has strong robust stability against the parameter variations, it can construct a more useful control system than H(infinity) control for a real control object.
