The controller transfer function and its digital implementation algorithm are derived by transforming a mass-spring layered structure into an equivalent uniform beam, whose wave propagation times among the boundaries, sensor and actuator positions are equal to those of the original mass-spring layered structure. When the actuator is at the top layer, the control can be determined only by the dead time rule. When the actuator is not at the top layer, the control is determined by the dead time rule and the convolution rule. The latter is transformed to the new fast algorithm in order to reduce the computation time since the controller impulse response function to be convoluted with the sensor output has no damping and the convolution integration range cannot be truncated. Time response analysis shows that by the present control, response can be reduced considerably without causing instability.
