The area of vibration control is evolving rapidly primarily due to the high demand of lightweight automotive structures. To achieve desired vibration characteristics of the product in field, extensive vibration testing is required of the product in a laboratory. In this study, a novel technique is presented for generating desired structural transient vibrations in a product in a laboratory. A cantilevered test-plate instrumented with piezoelectric patches is made to track desired transient vibration curves. Finite element technique is used for mathematical modeling and optimal tracking control is used to simultaneously track first three vibration modes of the plate. Presented strategy can be used to do dynamic vibration testing of a structure by forcing the structure to experience same transient vibrations that it is expected to experience while in field.
