In this report, we propose a theoretical essence of the stabilization of flexible structures by using the static output feedback control.This shows that not only strain outputs but also other outputs are valid in this control method for flexible structures of many boundary conditions including cantilevers, free ends, and other general boundary conditions. Sufficient conditions of structures and observation mechanisms are obtained for the closed loop systems to be asymptotically stable. When the observation mechanism is nicely chosen, the closed loop system becomes exponentialy stable.
