Abstract

This paper describes an experimental study on H control for vibration in multi-degree-of-freedom systems. An H 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 control system is confirmed. Also experiments on frequency-shaped cost function LQG (H2) control design are performed in comparison with the H optimal control. Because the H optimal control has strong robust stability against the parameter variations, it can construct a more useful control system than H control for a real control object.
