In the paper a novel robust controller design for switched discrete-time system is developed. Robust stability and performance is treated by pole-placement approach. LMI approximation of discrete-time pole region for prescribed stability degree and damping factor is employed. The respective robust stability condition for switched system is developed by applying Lyapunov stability condition on prescribed LMI pole region. The obtained results are illustrated by simulation example and application on laboratory plant. © 2014 IEEE.

The paper deals with the beam finite element, which is made from Functionally Graded Material (FGM) core and piezoelectric layers. In order to obtain effective material properties, homogenization of FGM core and homogenization of core and piezoelectric layers are used. In the paper, there is presented the derivation of individual submatrices of local stiffness matrix, where concept of transfer constants is used. Functionality of new FGM finite beam with piezoelectric layers is presented by numerical experiments.
