Abstract : Issues regarding the experimental interpretation of DE-based controllers are discussed in this work. The innovation motivating application involves the reduction of vibration levels for a circular plate through excitation of surface-mounted piezoceramic patches the general techniques described here will extend to a variety of applications. The initial step is the development of a PDE model which accurately captures the physics of the underlying process. This model is then discretized to yield a vector-valued initial value problem. Experimental results demonstrating the control of both transient and steady state vibrations through these techniques are presented. (MM)
