Abstract : The objectives of this program are aimed at the development of controls technology for Smart Structures and Materials systems with large numbers of sensors and actuators. This development focuses on a methodology for designing controllers that control large-scale Smart Structures and Materials systems with potentially thousands of inputs and outputs at a dramatically reduced cost in both computation and input/output interconnection complexity. Moreover, the methodology can be used to implement large-scale controllers that have highly scalable, multiprocessor architectures. Our program objectives can be summarized as follows: (1) Demonstrate an initial proof-of-concept of the wavelet-based method for controlling smart structures and materials with large transducer arrays. (2) Develop a practical and mathematically sound methodology for designing and implementing computationally efficient, sparsely interconnected, scalable control systems. (3) Validate the new methodology by designing and simulating a control system for control of simple structures using both numerical modeling data and experimentally measured data.
