This study discusses the vibration control of a plate structure supported with active suspension, replacing an elastic car body with a plate structure. Plate structures have typical distributed parameters. Hence, we designed a control system based on LQ control theory, building a six-particle physical model that controls the six-degree modes of bouncing, rolling, and pitching that include vibration modes of bending and torsion. These multiple modes were controlled in simulations and experiments, which verified that vibration in active suspension systems can be controlled.
