This project addresses improving the procedures for modeling                    structures.  Such modeling is critical in the design of                         mechanical systems.  Failure to use high fidelity models in the                 design process will only compromise the reliability of the final                product.  Techniques currently exist for determining the                        frequency response function for single input/output systems.                    The technique for more realistic multiple input/output systems                  is not yet developed.  This activity addresses that need.  This is a            four phase research study which develops for multiple input/output              systems a theory capable of generating accurate pole-zero models for            the dynamic response of structures.  In addition to estimating the              system parameters, the method can quantify the error of each                    estimated parameter.  The theoretical methods developed will be                 tested for a structure representative of the common problems                    associated with modal testing.  Results                                         of this work will have application beyond structural modeling.                  They will also be applicable to the technology of control of                    structural components and systems.
