This paper deals with the development of process for finding the optimal number and location of piezoceramic actuators and sensors to suppress the vibration of 2D systems. This choice must satisfy the condition of maximum possible system observability and controllability and is independent of the choice of control algorithm. Controllability and observability of the system is expressed via grammians of controllability and observability, respectively as product of these two items. The problem is solved by the optimization process in MATLAB program using a combination of library functions as well as its own created function and a set of input data from system model from program package ANSYS. Comparing the matrix product of grammians in the optimization process, serves as the main benchmark and its result is a set of indicia location of piezoceramic members.
