Paper Abstract

The approach to modeling and control of smart flexible structures presented in this paper is based on the claim that an intelligent structure requires an internal knowledge of self which may be acquired from local models of substructure dynamics. This approach employs analog models of the flexible structures in model-based controller designs. These analog models are created using VLSI circuitry and are embedded into the physical structure. The model of a composite structure is formed by interconnecting the analog models of single finite elements. The goal of this research is to devise such analog VLSI circuit models of single elements that can be easily connected together to model flexible structures. The circuit models are highly repetitive and, thus, are amenable to integration on a VLSI chip. A simple finite element circuit model has been integrated on an analog VLSI chip. Results clearly show that the poles of the circuits correspond very closely with the theoretical poles of the beam.
