This paper presents a vibration control method for a wire with time-varying length such as an elevator cable and a crane wire. The characteristics of the wire is varying with time, hence, a nonstationary controller which is designed depending on the time variation of controlled object is effective. Furthermore, since a wire is flexible structure, a spillover due to uncertainties and ignored high order modes is caused. Therefore, we propose the controller considering the robustness for the uncertainties of controlled system and its usefulness is verified through a numerical calculation.
