A general control differential equation of controlled constrained damping laminae is established. Experimental and theoretical modeling of a cantilever rectangular plate with a controllably constrained damping layer was carried out. The uncertainties in the model were analyzed in detail. The numerical simulation and experimental study of H∞ robust vibration control were carried out. The results show that H∞ control can effectively suppress the mode vibration of the controlled structure and has better robust stability than the displacement proportional feedback control.
