Abstract

This study demonstrates the feasibility of developing an integrated assembly of accurate and robust simulation tools for intelligent structures. Limitations of existing numerical models and cost associated with experimental models motivated this research. The emphasis is placed on the incorporation of structural analysis, plant modeling, control algorithm synthesis, optimization and performance evaluation into a single software package. The present paper includes finite element formulation of a coupled electromechanical smart structure with piezoelectric sensors and actuators, implementation of control design and evaluation of candidate control laws on the basis of finite element discretization. The discretized model predicts both mechanical and electrical responses due to the electromechanical loading and generates sensor output equations. An optimal independent modal space control is implemented and a rudimentary finite element-control package is developed to evaluate the performance of candidate control laws.
