內(nèi)容摘要：
In thistalkwe propose a novel and simple output feedback controller for a wave PDEs with unknown negative-damping coefficient. We also design a simple exponential stabilizing controller for the same wave PDEs but with the negative-damping coefficient assumed to be known knowledge. The striking feature of the proposed controllers is that it requires only one boundary displacement sensing, which is sharp contrast to the more than two boundary measurements or the entire distributed state of the systemin the existing literature. The key techniques is based on the stability property of a neutral differential equation which provide us the design of the gain parameter of controller.
