The central focus of the effort on this project has been the development of analog VLSI circuit models intended for use in distributed, model-based control of vibrations for flexible structures. The availability of piezo strain elements and memory alloys has created the possibility for actively controlled composite structures in which actuation is integrated with the structure. The advances in miniaturization of analog VLSI circuits allow analog models, controllers, and observers to be embedded directly on flexible structures with little increase in weight 1, 2, 3. Thus, a chip model of a substructure could be integrated directly into the controller and embedded in the substructure with the actuation. The research presented in this report has involved designing analog models of flexible structures for applications involving sophisticated embedded control applications.
