ABSTRACT

This article deals with the investigation of optimal actuator placement for two dimensional systems. In this article the two dimensional system is represented by a clamped

plate. The intention of optimal actuator placement is to place actuators in minimal number of actuators to ensure controllability of the system. In this article is compared placement of force actuators and piezoelectric actuators. The approach proposed in this article is based on the evaluation of the H2 and H∞ norms. The optimal actuator placement satisfies the condition of controllability.
