Optimal actuator and sensor placement with regard to coupled electro-mechanical behaviour of smart structures

By Tamara Nestorovic and Miroslav Trajkov

Abstract

In this paper the problem of optimal actuator and sensor placement for active large flexible structures is considered. The proposed placement optimization method is based on balanced reduced models. It overcomes disadvantages arising from demanding numeric procedures related with high order structural models. Optimization procedure relies on H2 and H∞ norms, as well as on controllability and observability Gramians, related with structural eigenmodes of interest. The optimization procedure is documented by examples, which show a good agreement between the results obtained using different placement indices
