Abstract

In this paper an investigation of a new formulation for active vibration control, which based on the optimal positions of piezoelectric sensors. The free vibration and modal properties are derived from the classical plate theory by using finite element method. A criterion is proposed to optimise the location of piezoelectric patches based on the observability Gramian of the structure and applied to a simply supported plate. The genetic algorithm is used to realise the optimal fitness function for finding the optimal configuration. The numerical simulation demonstrates that by locating piezoelectric sensors in the optimal positions, the energy delivery efficiency of the structure increases effectively.
