In this article, the optimal location and number of piezoelectric sensors is formulated for active vibration control. A modified criterion is used to ensure good observability of the system by considering the minimum number of needed piezoelectric elements. A genetic algorithm is proposed to solve this bi-objective optimization problem. Simulations are presented for a thin plate.
