Position of piezoelectric actuators and sensors on a smart structure directly affects the
control performances of a smart structure. In order to improve efficiency of active vibration
control of a smart structure, optimization of piezoelectric actuators and sensors placement has
been performed. There are various optimization criteria for optimal placement of piezoelectric
actuator. The ‘state-of-the-art’ of optimization criteria is presented in [1]. The aim of this paper is
to compare control effectiveness of smart composite cantilever beam, where optimal
configurations of actuator-sensor pairs were found by using four optimization criteria (LQR based
optimization, grammian matrices, performance index and fuzzy optimization strategy). The
problem is formulated as multi-input-multi-output (MIMO) model. The beam is discretized by
using the finite element method (FEM). The particle swarm optimization (PSO) method is used to
find optimal configurations for each configuration
