Abstract

A frequency domain model on the basis of a rectangular plate with symmetrically integrated piezo-elements is extended to time domain suitable to use for on-line active vibration control simulations. Electromechanical effects of piezoceramic elements such as mass, stiffness and actuation are included in the model. The model is coupled to a control simulator comprising both Feedforward and Feedback algorithms. Simulations are made using the model to investigate some important aspects that may be encountered in practice such as system identification and control performance for different configurations. Finally, both controllers are implemented in DSP boards and experiments are carried out. Results demonstrate the representativeness of the system model and the efficiency of the algorithms for a SISO system. It is noted that the model developed in this paper is accurate and flexible enough to represent the real system in a control situation. The whole on-line simulation process is capable of reproducing reliable results to guide implementation of controllers.
