This paper concerns with active vibration control of non-uniform damped mass-spring systems by the wave control. Especially, this study considers clarifying a class of a damped mass-spring system that can be analyzed by the wave-based analysis. Because the wave properties are determined by the propagation constants, three conditions for the propagation constants are considered. Necessary and sufficient condition for the physical parameters to hold the three conditions is obtained. Moreover, for this class of damped mass-spring systems, properties of the propagation constants and the characteristic impedances, which achieve the impedance matching, are studied. Numerical examples are shown to prove efficiency of the impedance matching controller.
