Non-Collocated Feedback Stabilization of a Kind of System Described by Wave Equations
Authors: , ,
Abstract: In this paper, we study the stabilization problem of a three-edge network system described by variable coefficients wave equations. With the root node fixed and a tip mass attached on the common vertex, we design two non-collocated controllers. Then we show that the closed-loop system is well-posed and satisfies spectrum- determined growth condition while the feedback gain constants fulfill some requirements. Moreover, we prove that the system is exponentially stable by applying Riesz basis method and utilizing some tricks of inequalities.
