Gilbert Stuart Room
Active materials used as actuators in engineering applications exhibit nonlinear hysteretic response. The control of deformations of active structures, especially under cyclic loading, is therefore a challenging problem. Currently, there are physically motivated constitutive models of active materials and empirical models based on identification procedures. The first group of models includes micromechanically based models, which are usually difficult to invert and implement in a real time control algorithm. The second group of models, even though it satisfies controllability criteria, includes ad-hoc physical assumptions and a large number of empirical constants. The aim of this minisymposium is to bring together experts working on each model to discuss common ground between the approaches.
