Output controllability in a long time horizon
In this article we consider a linear nite dimensional system. Our aim is to design a control such that the output of the system reach a given target at a nal time T > 0. This notion is known as output controllability. We extend this notion to the one of long time output controllability. More precisely, we consider the question: is it possible to steer the output of the system to some prescribed value in time T > 0 and then keep the output of the system at this prescribed value for all times t > T? We provide a necessary and sucient condition for this property to hold. Once the condition is satis ed, one can apply a feedback control that keeps the average xed during a given time period. We also address the L2-norm optimality of such controls. We apply our results to (long time) averaged control problems.
